typeof gax | typeof gax.fallback
: loaded instance of google-gax
. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: ``` const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new SpeechClient({fallback: 'rest'}, gax); ```

Performs bidirectional streaming speech recognition: receive results while sending audio. This method is only available via the gRPC API (not REST).
gax. CancellableStream
{Stream} An object stream which is both readable and writable. It accepts objects representing for write() method, and will emit objects representing on 'data' event asynchronously. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#bi-directional-streaming) for more details and examples.

Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED

.
