Hearing Assistance Apparatus Word-to-Audio Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies require users to manually search for specific portions of input speech for replay, and existing speech recognition systems do not allow users to listen to speech corresponding to inferred words.
Innovation Solution
A hearing assistance apparatus and method that includes a speech recognition information generating unit to infer words from input speech and associate them with corresponding speech information, and a speech output information generating unit to output the corresponding speech to a speech output device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current speech recognition technology is used, then speech recognition processing can be executed and words can be inferred, but users must manually search for audio corresponding to desired portions
Solution Approach 1:
The patent segments the speech recognition result into individual words or phrases, each associated with its corresponding audio segment. This allows users to access specific portions of speech without manually searching through the entire audio file, directly resolving the contradiction between ease of operation and time loss.
Solution Approach 2:
The patent introduces an intermediary structure (speech recognition information) that links words to their corresponding audio segments. This intermediary enables direct access to specific audio portions through word selection, eliminating the need for manual audio searching and reducing time loss.
2Adaptability or versatility
If speech recognition processing is executed on entire input speech, then complete speech information can be processed, but users cannot easily listen to speech corresponding to individual inferred words
Solution Approach 1:
The patent divides the speech recognition process into segments that map individual words or phrases to specific audio segments. This segmentation enables versatile access to speech information by word while maintaining manageable system complexity through structured data association.
Solution Approach 2:
The patent performs preliminary action by pre-associating words with their corresponding audio segments during speech recognition processing. This preliminary structuring enables later easy access to speech corresponding to individual words without adding complexity during the actual listening operation.
3Measurement precision
If users want to replay specific audio portions, then detailed listening can be achieved, but users must manually search through the entire audio
Solution Approach 1:
The patent implements feedback by providing users with a display of inferred words that reflects the speech recognition results. Users can select words from this feedback display to access corresponding audio segments, achieving precise location of speech portions without manual audio searching and reducing time loss.
Solution Approach 2:
The patent introduces an intermediary interface (word display and selection mechanism) that mediates between the user and the audio segments. This intermediary enables precise navigation to specific speech portions through word selection, eliminating the need for manual audio scanning and reducing time required to locate desired content.

AI summary
A hearing assistance apparatus including: a speech recognition information generating unit that executes speech recognition processing on first speech information to infer one or more words from the first speech information, and generates speech recognition information by, for each of the one or more inferred words, associating word information representing the inferred word with second speech information corresponding to the inferred word; and a speech output information generating unit that generates, using the second speech information corresponding to the one or more inferred words, speech output information for outputting, to a speech output device, second speech corresponding to the one or more inferred words.
