the class SpeechToText method recognizeUsingWebSocket.

/**
 * Sends audio and returns transcription results for recognition requests over a WebSocket connection. Requests and
 * responses are enabled over a single TCP connection that abstracts much of the complexity of the request to offer
 * efficient implementation, low latency, high throughput, and an asynchronous response. By default, only final
 * results are returned for any request; to enable interim results, set the interimResults parameter to true.
 *
 * The service imposes a data size limit of 100 MB per utterance (per recognition request). You can send multiple
 * utterances over a single WebSocket connection. The service automatically detects the endianness of the incoming
 * audio and, for audio that includes multiple channels, downmixes the audio to one-channel mono during transcoding.
 * (For the audio/l16 format, you can specify the endianness.)
 *
 * @param recognizeOptions the recognize options
 * @param callback the {@link RecognizeCallback} instance where results will be sent
 * @return the {@link WebSocket}
