如何使用Python从出站Twilio调用中检索信息并将其放入google speech to text？

import os
from twilio.rest import Client
from google.cloud import speech_v1p1beta1 as speech

# 设置Twilio和Google Cloud凭证
twilio_account_sid = "YOUR_TWILIO_ACCOUNT_SID"
twilio_auth_token = "YOUR_TWILIO_AUTH_TOKEN"
google_credentials_path = "YOUR_GOOGLE_CREDENTIALS_JSON_PATH"

# 创建Twilio和Google Cloud客户端
twilio_client = Client(twilio_account_sid, twilio_auth_token)
google_client = speech.SpeechClient.from_service_account_json(google_credentials_path)

# 获取Twilio出站调用的录音文件URL
call_sid = "YOUR_TWILIO_CALL_SID"
recording_url = twilio_client.calls(call_sid).recordings.list(limit=1)[0].uri

# 下载录音文件
download_path = "path/to/download/recording.wav"
os.system(f"curl {recording_url} -o {download_path}")

# 准备语音转文本请求
audio = speech.RecognitionAudio(uri=download_path)
config = speech.RecognitionConfig(
    encoding=speech.RecognitionConfig.AudioEncoding.LINEAR16,
    sample_rate_hertz=16000,
    language_code="en-US"
)

# 发送语音转文本请求
response = google_client.recognize(config=config, audio=audio)

# 解析并输出文本结果
for result in response.results:
    print("Transcript: {}".format(result.alternatives[0].transcript))
