Cannot use speaker diarization with streaming recognition

[lunard]

Hello to all! In my project I use both the “normal” speech recognition and the streaming (live) recognition, where the speaker diarization is fundamental.

Sadly the diarization (the result contains the wordInfo array) doesn’t seems to work with the streaming recognition (the array is empty)

someone faced the same problem ?

here my initialization (Node.is)

``` 
const config = {
encoding: 'LINEAR16',
sampleRateHertz: 16000,
languageCode: languageCode,
enableAutomaticPunctuation: true,
enableSpokenEmojis: { enabled: true },
diarizationConfig: {
enableSpeakerDiarization: true,
},
} as GoogleRecognitionConfig;

// // https://cloud.google.com/speech-to-text/docs/streaming-recognize
const streamingRecognitionConfig = {
config: config,
singleUtterance: true,
interimResults: true,
} as GoogleStreamingRecognitionConfig;

const stream = this.googleSpeechClient.streamingRecognize(streamingRecognitionConfig);

```
