What Is the Text to Speech Tool?
This free text to speech tool converts any written text into spoken audio using the Web Speech API built into your browser. Type or paste up to 5,000 characters, select a voice, adjust the speed and pitch, and press Play. The tool highlights each word as it is spoken, so you can follow along in real time.
Unlike cloud-based TTS services, your text never leaves your device. The speech synthesis engine runs entirely inside your browser, which means it works without an internet connection (once the page is loaded), has zero latency, and is completely private. No account required, no usage limits.
Use it for proofreading articles, studying notes, accessibility, learning pronunciation, or simply having text read to you while you do something else. The voice quality depends on your operating system, but modern browsers include dozens of high-quality voices across many languages.
How to Use Text to Speech
Step 1: Type or paste your text into the input box, or use the “Paste from clipboard” button. The tool supports up to 5,000 characters per session and shows a live word and character count.
Step 2: Choose a voice from the dropdown. Voices are grouped by language so you can quickly find English, Spanish, French, or any other language. Click “Preview voice” to hear a sample before committing.
Step 3: Adjust the speed, pitch, and volume using the sliders, or pick a speed preset like “Slow & Clear” for careful listening or “Fast” for quick reviews. The “Audiobook” preset uses a slightly slower rate with lower pitch for a comfortable, natural listening experience.
Step 4: Press Play. The reading preview panel highlights each word as it is spoken and auto-scrolls to keep your place visible. You can pause, resume, or stop at any time.
Key Features
Real-time word highlighting uses the SpeechSynthesis boundary event to track exactly which word the engine is reading. The current word is highlighted with a yellow background, making it easy to follow along or catch errors while proofreading.
50+ voices across multiple languages are available depending on your browser and OS. Chrome on Windows and macOS typically provides the most voices. You can select any voice and the engine will automatically use the correct pronunciation rules for that language.
Speed presets let you quickly switch between four common configurations: Slow & Clear (0.75x) for comprehension, Normal (1.0x) for standard playback, Audiobook (0.9x with lower pitch) for comfortable extended listening, and Fast (1.5x) for rapid review.
100% private and offline-capable. Everything runs in your browser using the Web Speech API. No text is transmitted to any server. Once the page is loaded, it works without an internet connection.
Frequently Asked Questions
How many voices are available?
The number of voices depends on your browser and operating system. Chrome typically offers 20-50+ voices, including many languages. Safari on macOS can have over 70 voices. Edge provides high-quality Microsoft voices. The voices are built into your system, so you always get natural-sounding results without any API calls.
Can I download the audio?
Browser-based text-to-speech cannot be captured directly as an audio file due to browser security restrictions. For downloadable speech audio, we recommend using our Voice Recorder tool while playing the text-to-speech output — this lets you record the audio through your system and save it as a file.
Does this support multiple languages?
Yes. The voice selector groups voices by language. Select a voice in the target language and the speech engine will read the text using that language's pronunciation rules. Available languages vary by browser but typically include English, Spanish, French, German, Italian, Portuguese, Chinese, Japanese, Korean, Hindi, Arabic, and more.
Is this tool really free?
Yes, completely free with no limits. This tool uses the Web Speech API built into your browser — there are no API costs, no usage caps, and no account needed. Your text never leaves your device. Everything runs locally in your browser, so it works even offline (as long as the page is already loaded).
How does the word highlighting work?
As the browser speaks each word, it fires a boundary event that tells us exactly which word is being spoken. We use this to highlight the current word with a yellow background in the reading preview panel. The display automatically scrolls to keep the highlighted word visible, making it easy to follow along.
