How to Use the Text to Speech Tool
This in-browser utility uses the native Web Speech API built into your web browser to read text aloud:
Input Text
Paste or type the text you want to hear into the editor, or click “Load sample” to test pronunciation.
Choose a Local Voice
Select from the verified local voices installed on your device. Only local voices are offered to safeguard privacy.
Tune Speaking Speed
Adjust the speed slider between 0.5x and 2.0x, or tap a preset to match your listening preference.
Control Playback
Click Speak to start. Pause and resume at any time, or click Stop to reset playback to the beginning.
Long Text Chunking Without Cutoffs
In many web browsers, single speech utterances that run longer than 15 to 20 seconds can freeze, pause unexpectedly, or stop speaking before finishing. To provide smooth and reliable text to speech reading for longer articles and documents, this tool automatically segments your text:
Natural Sentence Boundaries
Text is divided along punctuation marks (periods, question marks, exclamation points, and paragraph breaks). This ensures that natural pauses and cadence are preserved rather than breaking words in half.
Sequential Queue Management
As each sentence completes, the engine seamlessly triggers the next segment in sequence while updating the visual progress bar, giving you clear tracking of how much text remains.
Voice Availability and Sound Quality
Because this application uses standard browser speech synthesis rather than proprietary server-side audio generators, voice options and acoustic quality depend entirely on your current browser and operating system:
- Operating system speech engines: Windows, macOS, iOS, Android, and Linux provide their own native text to speech voices. For example, macOS and iOS provide Apple voices such as Samantha or Daniel, while Windows provides Microsoft David or Zira.
- Language and accent variety: The languages available in the selector reflect the voice packs installed on your device. You can often install additional language voices via your operating system settings.
- Naturalness and inflection: Audio fidelity is governed by the underlying hardware synthesizer on your system. Modern operating systems often provide enhanced or natural voice variants.
Accurate Privacy & Text Handling
Privacy is a primary architectural priority across FreeText. Here is exactly how text to speech operates:
Strict Local Voice Selection
The speech engine queries your browser and filters out any voice that is not marked with localService === true. Remote network voices that transmit text to external cloud servers are intentionally excluded.
No Server Storage
The application does not deliberately store entered text in user accounts, remote databases, or server-side logs. Your text stays inside your browser tab.
Browser Restoration Behavior
While our code does not persist your text between sessions, native browser features (such as reopening closed tabs or restoring form entries upon page reload) are controlled by your individual device and browser settings.
Practical Limitations
To set honest expectations, please keep the following technical boundaries in mind:
No Audio File / MP3 Downloads
The browser’s Web Speech API outputs synthesized audio directly to your physical speakers or headphones. The web standard does not provide an audio stream or file generation mechanism, so audio files cannot be exported or downloaded.
Background Tab Throttling
Some mobile and desktop operating systems pause background JavaScript timers when you switch tabs or lock your screen. For uninterrupted playback, keep the browser tab active during reading.
No Cloud or AI Voices
We do not simulate or connect to third-party generative AI speech APIs. All speech synthesis is carried out by the hardware engines already present on your machine.
Internet Needed for Page Assets
Although speech synthesis itself executes on your device, the web application assets (HTML, CSS, JavaScript) require an active network connection when loading the site.
Frequently Asked Questions
Why are some voices not listed in the selector?
Some browsers list remote network voices (such as Google cloud voices in Chrome) that transmit text to external servers for speech processing. To protect your privacy, this tool strictly permits only voices flagged as local to your device (localService === true).
Can I download the spoken speech as an MP3 or WAV audio file?
No. The browser’s SpeechSynthesis API plays audio directly through your device’s sound system without exposing raw audio byte buffers. We do not advertise or support audio recording downloads.
What happens if I edit the text while speech is playing?
To prevent reading outdated content, playback automatically stops as soon as you type or edit the text. You can then click Speak to listen to your updated text from the beginning.
How can I add more voices or languages?
You can install additional language voices through your computer or phone’s system settings (such as Accessibility or Speech settings in Windows, macOS, iOS, or Android). Once installed, refresh this page and the new local voices will appear in the selector.
