Python mp3转文字

Python中有多种库可以将MP3音频文件转换成文本，其中最常用的是通过语音识别技术实现这一功能。Tencent Cloud 的 `tencentcloud_asr` 库，Google的 `google-cloud-speech` 或者阿里云的 `aliyun-python-sdk-aip-asr` 都支持这种转换。下面是一个简单的例子：

from tencentcloud.common import credential
from tencentcloud.asr.v20190614 import asr_client

# 使用腾讯云的API
def mp3_to_text(mp3_file_path):
    cred = credential.Credential('your_access_key_id', 'your_access_key_secret')
    client = asr_client.AsrClient(cred, "ap-guangzhou", "v20190614")

    # 设置音频处理配置
    audio_config = {
        "SampleRate": 16000,
        "Format": "AMR",
    }

    with open(mp3_file_path, 'rb') as f:
        req = {
            "Audio": f.read(),
            "Language": "zh-CN",  # 如果是其他语言，请替换为相应语言代码
            "RecognitionConfidenceThreshold": 0.8,  # 可选，识别结果置信度阈值，默认0.5
            "AsrTaskType": "SpeechRecognition"  # 默认值
        }
        response = client.Recognize(req)
        return response["WordsResult"]["Items"]
