Browser voices
The listen button uses speechSynthesis and the voices this device already has.
Speech bench
Listen here, then save a voice file
Pick a voice installed on this device and press Listen. Download builds a separate WAV with VSH Voice, because browsers do not let a site record the system voice.
Files stay on this device. Nothing is uploaded.
What you can do
Speed and pitch
Those controls apply to the browser voice.
Downloadable WAV
VSH Voice is generated in this tab. It is a simple on-device voice, not a copy of the system one.
Kid-safe text
Blocked phrases are not spoken and are not saved.
Questions
Why is the download not the same voice I hear?
Browsers can play a system voice, but they do not give the site the audio. The WAV is a second, on-device voice so you still get a file.
Does the text go to a speech API?
No. Listening uses the browser. The file is synthesized locally.
What if the voice list is empty?
Some browsers load voices a moment later. You can still download the VSH voice file.
How long can the text be?
Listen keeps the first 500 characters. The WAV uses the first 280.
