This is the api for python to use funasr engine, only support 2pass server.
pip install websocket-client
apt install ffmpeg -y
support many audio type as ffmpeg support, detail see FunASR/runtime/funasr_api/example.py
```shell
# create an recognizer
rcg = FunasrApi(
uri="wss://www.funasr.com:10096/"
)
# recognizer by filepath
text=rcg.rec_file("asr_example.mp3")
print("recognizer by filepath result=",text)
# recognizer by buffer
# rec_buf(audio_buf,ffmpeg_decode=False),set ffmpeg_decode=True if audio is not PCM or WAV type
with open("asr_example.wav", "rb") as f:
audio_bytes = f.read()
text=rcg.rec_buf(audio_bytes)
print("recognizer by buffer result=",text)
#### streaming recognizer examples,use FunasrApi.audio2wav to covert to WAV type if need
rcg = FunasrApi(
uri="wss://www.funasr.com:10096/"
)
