Common Usage

We suggest you load the module via require, pending the stabalizing of es modules in node:

const { init, vadGRPCEngine, asrGRPCEngine } = require('@fanolabs/fano-grpc-client');
init(poolSize, sslParams = { caCertPath, pkPath, certificateChainPath });
const vadClient = new vadGRPCEngine(
    'fano-ms-online-speech-vad:50000?tipping_point=0.3&trail_silence=500',
    callId
);
vadClient.connet((err, res) => {
    if(!!err) {
        errorHandle(err);
        return;
    }
    const result = client.handleMessage(res);
    dataHandle(result)
});

const asrClient = new asrGRPCEngine(
    'fano-ms-online-speech-asr:50000',
    callId
);
asrClient.connet((err, res) => {
    if(!!err) {
        errorHandle(err);
        return;
    }
    const result = client.handleMessage(res);
    dataHandle(result)
})

API

send(bufferData, metadata, inputRate = 8000, inputBits = 16)

• bufferData 音频文件buffer(分片)。
• metadata metadata 可以包含sos、eos、call id等。
• inputRate 音频文件采样率。
• inputBits 音频文件字节数。

handleMessage(data)

• data response data

• Returns:
