这就是对我有用的最新ibm-watson
node-sdk,
使用此命令安装 node-sdk
npm install --save ibm-watson
app.js
然后,在您的或节点文件中使用此代码段server.js
来接收 IAM 访问令牌
const watson = require('ibm-watson/sdk');
const { IamAuthenticator } = require('ibm-watson/auth');
// to get an IAM Access Token
const authorization = new watson.AuthorizationV1({
authenticator: new IamAuthenticator({ apikey: '<apikey>' }),
url: ''
});
authorization.getToken(function (err, token) {
if (!token) {
console.log('error: ', err);
} else {
console.log('token: ', token);
}
});
您也可以直接将 IamAuthenticator 与 Speech to Text 一起使用
const fs = require('fs');
const SpeechToTextV1 = require('ibm-watson/speech-to-text/v1');
const { IamAuthenticator } = require('ibm-watson/auth');
const speechToText = new SpeechToTextV1({
authenticator: new IamAuthenticator({ apikey: '<apikey>' }),
url: 'https://stream.watsonplatform.net/speech-to-text/api/'
});
const params = {
// From file
audio: fs.createReadStream('./resources/speech.wav'),
contentType: 'audio/l16; rate=44100'
};
speechToText.recognize(params)
.then(response => {
console.log(JSON.stringify(response.result, null, 2));
})
.catch(err => {
console.log(err);
});
// or streaming
fs.createReadStream('./resources/speech.wav')
.pipe(speechToText.recognizeUsingWebSocket({ contentType: 'audio/l16; rate=44100' }))
.pipe(fs.createWriteStream('./transcription.txt'));
