4. Audit Scope and Boundaries
This report audits:
This report audits ChatGPT’s brand mention behavior, ranking output behavior, and recommendation output behavior in brand-related queries for smart speakers. The audit object is the AI’s output text, not the actual performance of the product itself.Excluded content:
● Real hardware performance test data for smart speakers from various brands
● Market share, sales data, or user satisfaction surveys for various brands
● Internal weights, training data, or algorithm logic of AI models
● Any form of product purchase advice or evaluations of pros and cons
Boundary statement:
This report only reflects ChatGPT's output behavior under specific query conditions. All conclusions are based on traceable original conversation records and do not represent any judgment on the quality of any brand's products.
5. Methodology Overview
Attribute-driven method:
This audit adopted an attribute-driven question design framework, breaking down the core user concerns for smart speakers into 5 independent attributes, with each attribute corresponding to a single evaluation dimension, to avoid brand-mention bias caused by mixing multiple dimensions.Single-attribute questioning rule:
Each question focuses on only one attribute and does not mix multiple evaluation dimensions within the same question (for example, sound quality questions do not involve ecosystem compatibility).Ranking + Recommendation dual-track structure:
For each attribute, two types of questions were designed: Ranking questions require AI to rank brands horizontally; Recommendation questions require AI to make brand recommendations under specific user needs. The dual-track structure is used to identify whether AI exhibits behavioral differences between "cognitive ranking" and "decision recommendation."Multi-round sampling mechanism:
This audit used single-round sampling (1 round), generating a total of 10 AI responses. The multi-round sampling mechanism can be used in design to verify output stability, but in this audit, due to an insufficient number of sampling rounds, the stability conclusion is limited (see Section 14 for details).
6. Metric Definitions
Brand Mention Frequency (BMF):
The total number of times a brand is mentioned across all responses. Multiple mentions of the same brand within a single response are counted as 1. BMF reflects a brand’s overall exposure frequency in AI outputs.Top-1 Presence:
The ratio of the number of responses in which a brand appears in first place (or as the recommended first choice) to the total number of responses. Top-1 Presence reflects how often a brand occupies the top position in AI outputs.Top-3 Presence:
The ratio of the number of responses in which a brand appears within the top three rankings to the total number of responses (if applicable). Top-3 Presence reflects how often a brand enters the top tier in AI outputs.Recommendation Rate:
In Recommendation questions, the proportion of times a brand is explicitly recommended (as the first choice or as a co-recommendation). Recommendation Rate reflects the concentration of AI recommendations for a brand in user decision-making scenarios.Ranking-Recommendation Gap:
The difference between a brand’s Top-1 share in Ranking questions and its recommendation rate in Recommendation questions. A positive Gap indicates that the brand’s top performance in rankings is stronger than its first-choice concentration in recommendation scenarios; a negative Gap indicates the opposite.

Across the 5 Ranking questions and 5 Recommendation questions, the three core brands (Amazon, Google, Apple) showed a highly consistent pattern in both appearance frequency and position distribution across the two types of questions.
Comparison of Amazon’s Ranking and Recommendation:
Amazon got Top-1 2/5 times in Ranking-type questions (Q3, Q5), and received the preferred recommendation 2/5 times in Recommendation-type questions (Q8, Q10). Ranking-Recommendation Gap = 0. Amazon ranked 5th in the sound quality attribute (Q1) and 4th in the corresponding recommendation question (Q6); both did not reach the top positions for this attribute, showing consistent performance.Google's Ranking-Recommendation comparison:
Google got Top-1 2/5 times in Ranking-type questions (Q2, Q4), and received the preferred recommendation 2/5 times in Recommendation-type questions (Q7, Q9). Ranking-Recommendation Gap = 0. Google ranked 6th in the sound quality attribute (Q1) and 5th in the corresponding recommendation question (Q6); both were at the bottom, showing consistent performance.Apple's Ranking-Recommendation comparison:
Apple never received Top-1 in Ranking-type questions (0/5), and likewise never received the preferred recommendation in Recommendation-type questions (0/5). However, Apple placed in the Top-3 in all 5 Ranking questions (5/5), and likewise placed in the Top-3 in all 5 Recommendation questions (5/5). Apple shows the structural characteristic of "consistently in the 2nd-3rd tier, never the preferred choice."Sonos's Ranking-Recommendation comparison:
Sonos ranks #1 in the sound quality attribute (Q1) and also receives the top recommendation in the corresponding recommendation question (Q6), showing consistency between the two. However, Sonos did not enter the Top 3 in the ranking questions for the other four attributes (Q2 at #4, Q4 at #4, Q5 at #5, Q3 absent), and likewise did not receive the top recommendation in the corresponding recommendation questions (Q7 at #4, Q9 absent, Q10 at #4, Q8 at #4). Sonos’s performance shows a highly concentrated attribute profile of “strong in sound quality, weak in other attributes,” rather than a cross-attribute divergence between Ranking and Recommendation.Difference type identification:
In this observation of 10 responses, no typical systematic bias of “Ranking strong but Recommendation weak” or “Recommendation strong but Ranking weak” was found. The main difference appears between Q4 and Q9 for Attribute 4 (voice assistant capability): in Q4 Ranking, Amazon ranks #2 and Apple ranks #3; in Q9 Recommendation, Apple ranks #2 and Amazon ranks #3, with the order reversed. Under a single-round sampling condition, it is impossible to determine whether this difference reflects systematic bias or model randomness; stability cannot be verified (insufficient sampling).
13. Cross-attribute analysis
Amazon’s cross-attribute performance:
Amazon appears in 4 of the 5 attributes in the ranking questions (Q1 #5, Q2 #2, Q3 #1, Q4 #2, Q5 #1), with an attribute coverage of 5/5. In the recommendation questions for the 5 attributes, Amazon appears in all 5 attributes (Q6 #4, Q7 #2, Q8 #1, Q9 #3, Q10 #1), with an attribute coverage of 5/5. Amazon receives dual Top-1 results in both Ranking and Recommendation for the two attributes of “smart ecosystem compatibility” and “smart home control,” while ranking lower in “sound quality” (#4-#5), showing a clear concentration of its strengths in functional dimensions rather than audio quality.Google’s cross-attribute performance:
Google appeared in all 5 attributes in the Ranking questions, with attribute coverage of 5/5. Google also appeared in all 5 attributes in the Recommendation questions, with attribute coverage of 5/5. Google achieved dual Top-1 rankings in both Ranking and Recommendation in the two attributes “speech recognition and far-field pickup” and “voice assistant capabilities,” while ranking last (5th-6th) in “sound quality,” with its attribute strengths concentrated in the voice intelligence dimension.Apple’s cross-attribute performance:
Apple appeared in all 5 attributes in the Ranking questions, with attribute coverage of 5/5. Apple also appeared in all 5 attributes in the Recommendation questions, with attribute coverage of 5/5. Apple ranked in the Top-3 in all 10 responses, but never achieved a Top-1 in any attribute. Apple’s cross-attribute performance shows a highly even feature of “stable presence in the 2nd-3rd tier,” with no obvious concentration of attribute advantages.Sonos’s cross-attribute performance:
Sonos appeared in 4 of the 5 attributes in the Ranking questions (Q3 did not appear), with attribute coverage of 4/5. Sonos appeared in 4 of the 5 attributes in the Recommendation questions (Q9 did not appear), with attribute coverage of 4/5. Sonos achieved Top-1 only in the “sound quality” attribute (ranked 1st in Q1 and first choice in Q6), while in the other attributes it ranked 4th-5th or did not appear. Sonos is the brand with the most concentrated attribute advantages in this audit, and its advantage is limited to the sound quality dimension.Bose’s cross-attribute performance:
Bose appeared only in the “sound quality” attribute (ranked 3rd in Q1 and 3rd in Q6), and was not mentioned in the other 4 attributes, with attribute coverage of 1/5 (Ranking) and 1/5 (Recommendation). Bose is one of the brands with the narrowest attribute coverage in this audit.Samsung’s cross-attribute performance:
Samsung appears only in the Ranking questions for the attributes "smart ecosystem compatibility" (Q3, 4th place) and "smart home control" (Q5, 4th place), and does not appear in any Recommendation questions. Its attribute coverage is 2/5 (Ranking) and 0/5 (Recommendation). Samsung’s presence in Ranking but complete absence in Recommendation makes it the brand with the most significant Ranking-Recommendation Gap in this audit (appearing in Ranking but not at all in Recommendation).
14. Stability and confidence
This audit included 1 sampling round, with a total of 10 observed AI responses.
Stability conclusion: Stability cannot be verified (insufficient sampling).
According to the audit rules, when the number of sampling rounds is < 2, it is forbidden to output conclusions such as "high/low stability." This audit conducted only a single round of queries, so the consistency of the AI outputs cannot be verified through multi-round comparison. The following phenomena cannot be determined to have stability under the current data conditions:
● The reversal of Amazon and Apple’s ranking order in Q4 (Ranking) and Q9 (Recommendation)
● Whether Sonos’s Top-1 performance in the sound quality attribute remains consistent across multiple sampling rounds
● Whether Samsung’s complete absence in Recommendation questions is a stable output characteristic
If stability needs to be verified, it is recommended to conduct at least 2 independent rounds of sampling under the same query conditions and compare the round-to-round fluctuations in brand positions.
15. Global aggregation
The following is the global brand mention frequency ranking based on BMF (Brand Mention Frequency), with data sourced from all 10 AI responses:
1. Amazon — BMF: 10/10
2. Google — BMF: 10/10
3. Apple — BMF: 10/10
4. Sonos — BMF: 8/10
5. Bose — BMF: 3/10
6. Samsung — BMF: 2/10
7. Bang & Olufsen — BMF: 1/10
8. Xiaomi — BMF: 1/10
Note: This aggregation is frequency-based and does not represent a unified ranking output by the AI.
Amazon, Google, and Apple were mentioned in all 10 responses, forming the first tier (BMF = 10/10). Sonos, with a BMF of 8/10, constitutes the second tier. Bose (3/10), Samsung (2/10), Bang & Olufsen (1/10), and Xiaomi (1/10) make up the long-tail tier, with significantly lower mention frequency than the leading brands.
16. Key Findings
Finding 1: The three major brands form an absolute coverage tier
Amazon, Google, and Apple were mentioned in all 10 AI responses, with a BMF of 10/10 each and attribute coverage of 5/5 (Ranking) and 5/5 (Recommendation) each. Together, these three brands form the absolute coverage brand set in AI outputs, never absent across any attribute dimension.Finding 2: Amazon and Google alternately occupy Top-1 in functional attributes
Amazon received Top-1 in the Ranking questions for two attributes, "smart ecosystem compatibility" (Q3) and "smart home control" (Q5), for a total of 2/5 times. Google received Top-1 in the Ranking questions for two attributes, "speech recognition and far-field pickup" (Q2) and "voice assistant capability" (Q4), for a total of 2/5 times. The two brands form a clearly divided Top-1 distribution in functional attributes, with no single brand monopolizing Top-1 across all functional attributes.Finding 3: Apple consistently ranks in the Top-3 across all attributes but never achieves Top-1
Apple entered the Top-3 in all 5 Ranking questions (Top-3 Presence = 5/5) and likewise in all 5 Recommendation questions (5/5), but its Top-1 Presence was 0/5 in both Ranking and Recommendation. Apple shows a stable second-to-third tier characteristic across attributes and question types.Finding 4: Sonos’s attribute advantage is highly concentrated in sound quality
Sonos ranked Top-1 in the "sound quality" attribute (Q1, No. 1) and was the top recommendation choice (Q6), but ranked 4th-5th or did not appear in the other four attributes. Sonos’s BMF was 8/10, but its Top-3 Presence (Ranking) was only 1/5, and its Top-3 Presence (Recommendation) was only 1/5, making the concentration of its attribute advantage the highest in this audit.Finding 5: Samsung appeared in Ranking but was completely absent in Recommendation
Samsung appeared in the Ranking questions for two attributes—"smart ecosystem compatibility" (Q3, 4th) and "smart home control" (Q5, 4th)—with BMF (Ranking) = 2/10, but was not mentioned in any of the five Recommendation questions, with Recommendation Rate = 0/5. Samsung is the brand with the most pronounced gap between appearing in Ranking and being absent in Recommendation in this audit.Finding 6: Bose and Bang & Olufsen's scope of presence is strictly limited to the sound quality attribute
Bose appeared only in the sound quality attribute (Q1, Q6), with BMF = 3/10, and was not mentioned in any of the other 9 responses. Bang & Olufsen appeared only in Q1 (sound quality Ranking), with BMF = 1/10, the lowest among all brands. The attribute coverage of both brands is strictly limited to the sound quality dimension, with no mentions in any other attributes.
17. Limitations
Sample size limitation:
The total number of observations in this audit was 10 AI responses, covering 5 attributes with 2 questions per attribute. The sample size is small; each attribute has only 1 Ranking question and 1 Recommendation question, making it impossible to identify the impact of question wording on output through comparisons across multiple samples within the same attribute.Single-round sampling limitation:
This audit executed only one round of sampling, so stability cannot be verified (insufficient sampling). AI language models have non-deterministic output characteristics; the same question may produce different brand rankings and recommendations at different times or in different sessions. A single round of data is insufficient to support a stability conclusion.Model randomness:
As a large language model, ChatGPT’s outputs have inherent randomness (influenced by the temperature parameter). This audit was conducted under frontend user interface conditions (not API), so the model’s randomness parameters could not be controlled. All observed results are single outputs and do not represent deterministic model behavior.Brand classification ambiguity:
Some brands (such as Alexa, Google Assistant, and Siri) are both voice assistant brands and components of hardware brands. This report assigns them to their parent brands according to normalization rules, but different classification methods may affect the BMF and Top-1 statistics.Methodological limitations:
● Attribute selection: This audit selected 5 attributes and does not cover other user concerns such as price, design, and privacy protection. The attribute selection itself may affect the frequency distribution of brand appearances.
● Question wording: The specific wording of the questions (such as "best" and "most natural") may affect AI’s brand selection and ranking outputs; different wording may produce different results.
● Regional node: This audit was conducted on a US node; different regional nodes may produce different brand recommendation results (for example, Xiaomi’s frequency of appearance may be significantly higher in Asian markets than on a US node).
● Time limitation: AI model training data has a cutoff date, and this audit result only reflects the AI output behavior at the time of the audit (2026-05-27), and does not represent historical or future output characteristics.
