# How to Translate Speech

* [ ] Get a token
* [ ] Create ~~SpeechConfig~~ **SpeechTranslationConfig** object
* [ ] Define the recognition language
* [ ] Create an AudioConfig object from microphone stream
* [ ] Create a ~~SpeechRecognizer~~ **TranslationRecognizer** object

```javascript
async sttFromMic() {
    this.setState({
      displayText: "speak into your microphone...",
    });

    const tokenObj = await getTokenOrRefresh();
    const speechConfig =
      speechsdk.SpeechTranslationConfig.fromAuthorizationToken(
        tokenObj.authToken,
        tokenObj.region
      );
    speechConfig.speechRecognitionLanguage = "en-US";
    options.forEach((option) => {
      speechConfig.addTargetLanguage(option.value);
    });

    const audioConfig = speechsdk.AudioConfig.fromDefaultMicrophoneInput();
    const recognizer = new speechsdk.TranslationRecognizer(
      speechConfig,
      audioConfig
    );

    recognizer.recognizing = (s, e) => {
      console.log("recognizing ", e);
      let result = "";
      if (e.result.reason == ResultReason.RecognizedSpeech) {
        result = `TRANSLATED: Text=${e.result.text}`;
      } else if (e.result.reason == ResultReason.NoMatch) {
        result = "NOMATCH: Speech could not be translated.";
      }
      console.log(result);
      this.setState({
        tr: e.result.translations.get("tr"),
        es: e.result.translations.get("es"),
        it: e.result.translations.get("tlh-Latn"),
        displayText: e.result.text,
      });
    };

    recognizer.recognized = (s, e) => {
      console.log("recognized ", e);
      this.setState({
        displayText: `RECOGNIZED: ${e.result.text}`,
        tr: e.result.translations.get("tr"),
        es: e.result.translations.get("es"),
        it: e.result.translations.get("tlh-Latn"),
      });
    };

    recognizer.startContinuousRecognitionAsync();
```

```javascript
    recognizer.recognizeOnceAsync((result) => {
      if (
        result.reason === ResultReason.RecognizedSpeech ||
        result.reason === ResultReason.RecognizedSpeech
      ) {
        this.setState({
          displayText: "SPEECH_RECOGNIZED: " + result.text,
          translatedText: "Translated: " + result.translations[0].text,
        });
      } else if (result.reason === ResultReason.Canceled) {
        const cancellation = speechsdk.CancellationDetails.fromResult(result);
        this.setState({
          displayText:
            "CANCELED: Reason=" +
            cancellation.reason +
            ", ErrorDetails=" +
            cancellation.errorDetails,
        });
      }
    });
```
