IconVault's Speech Playground is a two-in-one speech studio that runs entirely in your browser. The transcription panel uses the real SpeechRecognition API with live interim results and accumulating final text in ten languages, while the text-to-speech panel speaks through speechSynthesis with your device's actual voices, adjustable rate, and pitch. It is free and nothing is uploaded.

If your browser lacks speech recognition, the mic panel says so honestly and stays disabled instead of faking it. The TTS voice list is read live from your operating system, so what you hear is exactly what your users would hear. Dictate notes, test voice UX copy, or explore how the Web Speech API behaves before you ship it.
