Why Is the Recognition Result Very Poor?

Symptom

The recognition result obtained after calling the ASR API is of great difference from the actual result, or the server reports an audio format error.

Solution

1. Check whether the audio sampling rate meets the requirements.

   You can use tools such as the toolsoft Audio player to listen to a raw audio file and adjust the sampling rate. When the audio file can be played properly, the sampling rate can be used.

2. Check whether the sampling rate part in the value of parameter property is the same as the actual sampling rate. For example, in chinese_8k_common, 8k is the sampling rate.
