如何在Python中使用IBM Bluemix中的语音转文本和文本转语音API

pip install requests

import requests
import json

def speech_to_text(audio_file):
    url = "语音转文本API的URL"
    headers = {
        "Content-Type": "audio/flac",
        "Authorization": "Bearer API密钥"
    }
    audio = open(audio_file, "rb").read()
    response = requests.post(url, headers=headers, data=audio)
    result = json.loads(response.text)
    return result["results"][0]["alternatives"][0]["transcript"]

def text_to_speech(text, output_file):
    url = "文本转语音API的URL"
    headers = {
        "Content-Type": "application/json",
        "Authorization": "Bearer API密钥"
    }
    data = {
        "text": text
    }
    response = requests.post(url, headers=headers, json=data)
    audio = response.content
    with open(output_file, "wb") as f:
        f.write(audio)
