Local Speech Recognition Response Control Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice interaction systems face delays in response time due to network access, general-purpose speech recognition supporting various utterances, and increased processing loads on servers, leading to reduced user convenience.
Innovation Solution
An information processing device and method that utilize a response control unit to manage user responses based on both first and second utterance interpretation results, where the second result is acquired through learning data associated with the first result, allowing for faster processing and reduced response time by performing local-side voice interaction tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If speech recognition processing is performed by both client and server to improve accuracy, then recognition accuracy is improved, but response time increases
Solution Approach 1:
The system performs preliminary speech recognition processing on the client side before server processing. The client generates a first recognition result locally, which is then used by the server to generate a second recognition result. This preliminary local processing reduces the overall response time while maintaining accuracy through subsequent server-side refinement.
Solution Approach 2:
The speech recognition system is divided into two segments: client-side processing and server-side processing. The client handles initial recognition and generates first recognition results, while the server performs additional processing to generate second recognition results. This segmentation allows parallel processing and reduces the total time required for accurate recognition.
2Adaptability or versatility
If general-purpose speech recognition is used to support various utterances, then adaptability is improved, but processing load on server increases
Solution Approach 1:
The system performs partial speech recognition processing on the client side rather than relying entirely on server processing. The client generates first recognition results locally, reducing the amount of processing required on the server while still supporting various utterances through the combined client-server approach.
3Measurement precision
If network access is required for speech processing, then recognition accuracy is improved, but response time increases
Solution Approach 1:
The system performs preliminary speech recognition processing on the client side before server processing. The client generates a first recognition result locally, which is then used by the server to generate a second recognition result. This preliminary local processing reduces the overall response time while maintaining accuracy through subsequent server-side refinement.
Data Source
AI summary
Provided is an information processing device including a response control unit that controls a response to a user's utterance based on a first utterance interpretation result and a second utterance interpretation result. The first utterance interpretation result is a result of natural language understanding processing for an utterance text generated by automatic speech recognition processing based on the user's utterance and the second utterance interpretation result is an interpretation result acquired based on learning data in which the first utterance interpretation result and the utterance text used to acquire the first utterance interpretation result are associated with each other. The response control unit further controls the response to the user's utterance based on the second utterance interpretation result in a case where the second utterance interpretation result is acquired based on the user's utterance before acquisition of the first utterance interpretation result.
