📖 Technical Reference for Client-Side Text to Speech
Speech Synthesis via Browser Web APIs
Text-to-Speech (TTS) technology converts written text into vocal audio. Modern web browsers include a built-in SpeechSynthesis engine as part of the Web Speech API. This allows developers to synthesize speech using the operating system's native text-to-speech voices directly in the browser.
Because the speech synthesis runs locally on your device, it requires no internet connection and consumes zero external API keys or subscription fees. You can adjust the speaking rate, pitch, and choose from various installed local voices.
How Free Audio Downloading Works
While browsers synthesize speech natively, they do not provide a direct button to save the audio as a file. To resolve this, our tool records the synthesized audio output. We route the spoken audio into a Web Audio API MediaStreamAudioDestinationNode, capture the stream using the MediaRecorder API, and record it into a standard audio buffer.
Once the text has been spoken, the audio buffer is compressed into a standard audio file (WebM or WAV format) and downloaded to your computer. This entire pipeline operates client-side, making audio conversion fast, secure, and completely free.
