Speech SDK Chinese recognition error

Jiaping Zhang 20 Microsoft Employee

Hi,

I've encountered an issue with recognizing Chinese characters. The system often returns English words instead, and the pronunciation isn't quite right. I've already set the speech recognition language to zh-CN. How can I improve this?

Thank you.

Best,

Penny

Hi Jiaping Zhang,

Greetings & Welcome to the Microsoft Q&A forum! Thank you for sharing your query.

To improve the recognition of Chinese characters using the Speech SDK, can you please these steps.

Make sure that the audio input is clear and free from background noise. Poor audio quality can lead to misrecognition.

Ensure that the audio is in a supported format, such as WAV. Unsupported codecs can cause issues with recognition.

If there is a long stretch of silence at the beginning of the audio, the service may stop recognition prematurely. It's advisable to avoid long silences when using single-shot recognition.

Double-check that the speech recognition language is correctly set to zh-CN. This is crucial for accurate recognition of Mandarin Chinese.

If certain phrases are consistently misrecognized, try testing with different phrases or pronunciations to see if the issue persists.

I hope this helps you. Thank you.
