<h3>This is a premium version of the captioning tool, with enhanced speech-to-text transcription & language translation.</h3>
The overlay-friendly output of the translated text is mirrored here: <a id="shareLink" href="overlay.html" target='_blank'>*ERROR GENERATING LINK*</a>.
<br /><br />
To use this app, accept the microphone permissions on page load and then just say something outloud. Once working, enable the transcription.
<br /><br />
Please note that this app uses your default microphone as the audio input source.
You sometimes can change the default audio source via the browser's setting, but you can also change it at your system level by changing the default recording device.
You can also change audio sources by using a Virtual Audio Cable, <a href='https://www.vb-audio.com/Cable/'> such as this one.</a>
Using it, it becomes possible to select other sources, including microphones, speakers, and other applications.
<br /><br />
The translation is powered by Google Cloud Translation, which <a href='https://console.cloud.google.com/apis/api/translate.googleapis.com/credentials' target="_blank">requires an API key.</a> (add &key=xxxxxxx to the URL to specify it). <br /><br /><div style='color:red'>I no longer offer access with my own API key, due to heavy and costly abuse.</div> You will need to get your own Google API key if you wish to use this premium version of the service.
