Speech Interaction Feedback Interface for ASR and NLU Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Speech interactions are prone to errors due to inaccuracies in automatic speech recognition (ASR), natural language understanding (NLU), and text-to-speech (TTS) conversion, leading to suboptimal user experience.
Innovation Solution
A graphical user interface is provided for users to give feedback on speech interaction performance, allowing corrections to be incorporated into the statistical models used by the speech interface platform, thereby improving ASR, NLU, and TTS accuracy over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If speech recognition and natural language understanding are used to enable hands-free interaction, then ease of operation is improved, but measurement precision deteriorates due to errors in speech interpretation
Solution Approach 1:
The system presents transcribed speech and generated responses to users for review and correction. Users can modify transcriptions and provide feedback on accuracy, which is then used to improve the statistical models. This feedback loop continuously enhances speech recognition accuracy while maintaining ease of hands-free operation.
2Adaptability or versatility
If statistical models are used for speech recognition and text-to-speech conversion, then adaptability is improved, but manufacturing precision deteriorates due to model inaccuracies
Solution Approach 1:
The system performs speech-to-text conversion and generates draft responses before presenting them to users. This preliminary processing allows users to review and correct the content, and the corrections are stored as training data to improve future conversions, thereby enhancing accuracy while maintaining adaptability.
Solution Approach 2:
User corrections to transcribed speech and generated responses are captured and used to retrain statistical models. This feedback mechanism continuously improves the precision of speech recognition and text-to-speech conversion while preserving the system's adaptability to various speech patterns and languages.
3Reliability
If user feedback mechanisms are added to correct speech interactions, then reliability is improved, but device complexity increases due to additional interface components
Solution Approach 1:
The graphical user interface serves multiple functions: it displays transcribed speech, presents generated responses, allows user corrections, and provides feedback submission. By consolidating these functions into a single interface, the system improves reliability through user feedback while minimizing the increase in apparent device complexity.
Data Source
AI summary
An interactive system may be implemented in part by an audio device located within a user environment, which may accept speech commands from a user and may also interact with the user by means of generated speech. In order to improve performance of the interactive system, a user may use a separate device, such as a personal computer or mobile device, to access a graphical user interface that lists details of historical speech interactions. The graphical user interface may be configured to allow the user to provide feedback and/or corrections regarding the details of specific interactions.
