Speech recognition accuracy: The speech recognition accuracy of different chips may be different, and the appropriate accuracy needs to be selected according to the specific application requirementsLevel. Processing speed and efficiency: The processing speed and efficiency of the voice recognition chip directly affect the response time and performance of the system, and it is necessary to choose the appropriate processing capability according to the actual application scenario.
Voice chip hardware quality: the better the quality of the voice chip hardware, its anti-interference ability will be improved accordingly. In general, improving the stability of the voice chip needs to consider a number of aspects, including quality control, temperature control, power control, a variety of power supply methods, physical protection and software upgrades.
chip algorithm quality: offline speech recognition chip performance dependsIts built-in recognition algorithm. The accuracy and robustness of the algorithm will directly affect the accuracy of the recognition. Speech quality: The clarity, sound quality, and level of interference of speech affect the accuracy of recognition.
And chip design needs to take into account audio processing capabilities and circuit design to ensure high-quality audio output. To sum up, the sound quality of OTP voice chips is affected by a combination of several factors, including sampling rate, resolution, DAC performance, digital-analog hybrid technology, application environment, as well as sound coding algorithms and chip design.
