Python版本讯飞语音“语音听写”Demo

语音听写，可以将60s以内的音频文件转换为文字

1.进入“讯飞开放平台”，创建“WebAPI”平台的应用

添加服务

 

把你的IP添加白名单，就可以进行测试了

audioFilePath = r"test.pcm"

r = requests.post(URL, headers=getHeader(aue, engineType), data=getBody(audioFilePath))
r2 = r.content.decode('utf-8')

dictinfo = json.loads(r2)

#得到语音转换为文字的数据
dictinfo["data"]

print(dictinfo["data"])

讯飞的转换结果有标点符号，准确率高，耗时短，能力强。
