我正在尝试使用Google Cloud Speech API（异步）转录一个简短的采访音频文件，但它只转录录制的前半分钟 . 我有几次尝试录音的时间超过一分钟，结果是一样的 . 我的问题是，如何实现给定文件的完整音频转录？
你可以在这里找到我的一个用例：
上传音频文件：
POST https://speech.googleapis.com/v1beta1/speech:asyncrecognize?key={YOUR_API_KEY} { "config": { "encoding": "LINEAR16", "sampleRate": 16000, }, "audio": { "uri": "gs://protean-blend-146812.appspot.com/record__2017_02_02_12_02_17_greg_16000.wav", } }
获得响应中的操作号：
{ "name": "8977932499808116064" }
使用操作号发出请求：
GET https://speech.googleapis.com/v1beta1/operations/8977932499808116064?key={YOUR_API_KEY}
得到了结果：
{ "name": "8977932499808116064", "metadata": { "@type": "type.googleapis.com/google.cloud.speech.v1beta1.AsyncRecognizeMetadata", "progressPercent": 100, "startTime": "2017-02-02T11:21:41.346784Z", "lastUpdateTime": "2017-02-02T11:23:03.150491Z" }, "done": true, "response": { "@type": "type.googleapis.com/google.cloud.speech.v1beta1.AsyncRecognizeResponse", "results": [ { "alternatives": [ { "transcript": "McGregor you have any stories about being lost that you have all the good advice well let me know in the Golden Triangle drug trafficking across the border", "confidence": 0.8535113 } ] }, { "alternatives": [ { "transcript": "we came across this Village very very poor Village People and some of the people there were really unfriendly they just started throwing rocks and my friend and we couldn't talk so we backed away went back quickly up the hill", "confidence": 0.9027881 } ] }, { "alternatives": [ { "transcript": "and we are wondering you know where to go and luckily I can see in the distance there in one tree", "confidence": 0.8931573 } ] } ] } }
