python call Baidu AI speech recognition

1, enter Baidu AI official website registered account and speech recognition services, create a voice recognition application

AI get Baidu application AppID, API Key, Secret Key

2, python code for AI voice calls Baidu platform

2.1, install python library

(1), pyAudio library
the library because of the need c ++ dependent, can not be used directly pip installed directly, we need to download the installation file whlee
github Address: https://github.com/intxcc/pyaudio_portaudio/releases

See here: https://blog.csdn.net/qq_36387683/article/details/91960141

Open the file directory:

pip install PyAudio-0.2.11-cp37-cp37m-win_amd64.whl

(2) \ wave, installation baidu-aip library

See here: https://blog.csdn.net/alice_tl/article/details/97434261

pip install wave

pip install baidu-aip

2.2, the code calls

            frames.append(data)
        print("*" * 10, "录音结束\n")

        stream.stop_stream()
        stream.close()
        p.terminate()

        wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
        wf.setnchannels(CHANNELS)
        wf.setsampwidth(p.get_sample_size(FORMAT))
        wf.setframerate(RATE)
        wf.writeframes(b''.join(frames))
        wf.close()
    elif aa == str("否"):
        exit()
    else:
        print("无效输入，请重新选择")
        get_audio(in_path)


if __name__ == '__main__':
    for i in range(1):
        get_audio(in_path)
        Speech()

The recognition result is great! ! ! !
