如何使用Python调用阿里云的实时语音识别API？

首先需要安装pyaudio第三库

然后获取您的阿里云DashScope API密钥，并在代码中设置

导包：
import pyaudio
from dashscope.audio.asr import Recognition, RecognitionCallback, RecognitionResult

设密钥：
dashscope.api_key = 'YOUR-DASHSCOPE-API-KEY' # 使用您的API密钥替换此处

回调类：

class Callback(RecognitionCallback):
    def on_open(self) -> None:
        global mic, stream
        print('RecognitionCallback open.')
        mic = pyaudio.PyAudio()
        stream = mic.open(format=pyaudio.paInt16, channels=1, rate=16000, input=True)

    def on_close(self) -> None:
        global mic, stream
        print('RecognitionCallback close.')
        stream.stop_stream()
        stream.close()
        mic.terminate()
        stream = None
        mic = None

    def on_event(self, result: RecognitionResult) -> None:
        print('RecognitionCallback sentence: ', result.get_sentence())

然后说初始化：callback = Callback()
recognition = Recognition(model='paraformer-realtime-v2', format='pcm', sample_rate=16000, callback=callback)
recognition.start()

while True:
if stream:
data = stream.read(3200, exception_on_overflow=False)
recognition.send_audio_frame(data)
else:
break

recognition.stop()
