Electronic Device Wakeup Audio Selection Using TTS and Voice Print
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device wakeup technologies can only provide a single prompt tone, limiting the variety of wakeup prompts and failing to offer personalized experiences.
Innovation Solution
An electronic device-awakening method and apparatus that selects an audio data file from multiple options based on a user's speech wakeup instruction, using Text-to-Speech (TTS) technology to generate and store various audio files, and employing voice print features for personalized prompts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single prompt tone is used for wakeup, then the device structure is simple, but the wakeup prompt variety is limited
Solution Approach 1:
The system pre-generates multiple audio data files with different prompt tones using TTS technology before the wakeup event occurs. These files are stored in advance in the audio module, so when a wakeup instruction is received, the system can directly select and play from the pre-prepared files without real-time generation, thus achieving prompt variety while maintaining simple real-time processing
Solution Approach 2:
The system changes the parameter of audio characteristics by generating multiple audio files with different sound parameters (such as different voices, tones, or styles) through TTS technology. This allows the same wakeup function to present different auditory experiences by selecting from files with varied audio parameters, thereby increasing wakeup prompt variety without adding hardware complexity
2Adaptability or versatility
If multiple audio data files are stored, then the wakeup prompt variety increases, but the storage space requirement increases
Solution Approach 1:
Instead of storing multiple pre-recorded audio files, the system uses TTS technology to generate audio files on-demand from text templates. The text templates occupy minimal storage space, while the actual audio files are generated as needed and can be discarded after playback. This copying approach replaces large storage requirements with small template storage plus temporary audio generation
Solution Approach 2:
The system generates and plays audio files periodically or on-demand rather than continuously storing all possible audio variations. When a wakeup event occurs, the system generates the necessary audio file, plays it, and then discards it. This periodic generation and disposal pattern reduces overall storage requirements while maintaining prompt variety availability
3Measurement precision
If voice print recognition is implemented for personalized prompts, then the personalization accuracy increases, but the processing complexity increases
Solution Approach 1:
The system performs voice print recognition in advance during the user setup phase, storing the extracted voice features for later comparison. When a wakeup instruction is received, the system quickly compares the incoming voice against the pre-stored voice print features to identify the user and select the corresponding personalized audio file. This preliminary extraction and storage of voice features reduces real-time processing complexity while maintaining high recognition accuracy

AI summary
The present disclosure provides an electronic device-awakening method and apparatus, a device and a computer-readable storage medium. In embodiments of the present disclosure, the user's speech wakeup instruction which is used to awaken the electronic device is obtained, and then an audio data file is selected from at least two audio data files according to the speech wakeup instruction, as a wakeup answer file of the electronic device, so that the wakeup answer file of the electronic device can be played. Since there are more than one selectable audio data files, many types of prompt tones can be provided, thereby achieving the purpose of providing many types of wakeup prompts.
