如何将音频片段文件转换为bytes类型？

Question

我想从 wav 中进行语音识别。 为此，我将一个 wav 分成多个块，导出它们，然后使用 SpeechRecognition 库。

from pydub import AudioSegment
import speech_recognition as sr

r = sr.Recognizer()
for i in range(5):
    audio = AudioSegment.from_wav("some_wav.wav")
    audio_chunk=audio[int(i*1000):int(i*3000)]
    audio_chunk.export('test.wav', format='wav')
    detection = sr.AudioFile('test.wav')

    with detection as source:
        audio = r.record(source)

    word = r.recognize_google(audio, language = 'ro-RO')

问题是这不是很理想。我想去掉导出的 wav 部分。我想将audio_chunk转换为字节，然后在speechRecognition.AudioFile()中使用内存字节。

有没有办法将音频段类型转换为字节？

晚了一年，但试试这个：

from pydub import AudioSegment
import speech_recognition as sr
import io

r = sr.Recognizer()
for i in range(5):
    audio = AudioSegment.from_wav("some_wav.wav")
    audio_chunk = audio[int(i*1000):int(i*3000)]
    
    buffer = io.BytesIO()
    audio_chunk.export(buffer, format="wav")
    detection = sr.AudioFile(buffer)

    with detection as source:
        audio = r.record(source)

    word = r.recognize_google(audio, language='ro-RO')
