What are the important technical differences between Chinese speech recognition and English speech recognition

1. Recognition and understanding of natural language. Firstly, continuous speech must be broken down into units such as words and phonemes, and secondly, a rule for understanding semantics must be established.

2. Speech is informative. Speech patterns are different not only for different speakers but also for the same speaker; for example, a speaker's speech information is different when he or she speaks casually and when he or she speaks seriously. A person's speech pattern changes over time.

3. Ambiguity of speech. When a speaker is speaking, different words may sound similar. This is common in English and Chinese.

4. The phonetic properties of individual letters or words or characters are affected by the context in such a way as to change the stress, pitch, volume and speed of pronunciation.

5. Environmental noise and interference have a serious impact on speech recognition, resulting in low recognition rates.
