Browser Test Client

Switch between service TTS and browser speech for a direct comparison.

Use the same text box and controls to compare the WebSocket TTS service against the browser Speech API. Service mode streams `webm/opus` back into the audio element, while browser mode speaks locally through the browser's native voice stack.

Server URL: Not connected

Text

In service mode, the page assumes the server is serving this file. If not, enter the WebSocket URL manually. The helper also expects Kokoro assets to be configured on the server side.

Playback

WebSocket audio is streamed into the audio element below. Browser Speech API playback uses the browser's native speech output instead.
