Speech & Voice Tools – Complete Voice & Translation Suite
See more
Slim ABBAR and Hafedh KHAYATI built this page after struggling to find a free, private voice tool that didn't require an account or send audio to some server. Three tools, one page: dictate, read aloud, and translate speech in real time — without installing anything.
Everything runs inside your browser. No account, no uploads, no server-side processing: your microphone is used only while you record, then the data stays on your device.
- Speech to Text: turn your voice into clean text for notes, emails, captions, or transcripts.
- Text to Speech: listen to any text with selectable voices and adjustable speed.
- Speech → Translate → Speech: speak, translate to another language, then listen to the translated result.
Languages: English, French, Arabic, Spanish, German, Portuguese, Russian, Chinese, Japanese, and more.
💡 Tip: Chrome or Edge gives the best compatibility. Arabic TTS works best in Microsoft Edge on Windows (includes Arabic Neural voices). On other browsers, install an Arabic language pack on your device.
Last updated: May 2026 · For the best experience, allow microphone access when prompted and keep your browser tab active while recording or listening. Chrome or Edge usually provides the best results for speech features.
⚡ Quick Start Guide
Quick start: start with Speech to Text if you want to dictate notes, switch to Text to Speech when you want written text read aloud, then use the voice translator when you need to speak, translate and listen in another language from the same page.
Tool 1 – Speech to Text (Multilingual Dictation)
How Speech-to-Text Became Possible: All the Sciences Behind It
Read more
No single scientist invented speech recognition. It is the result of at least six distinct scientific disciplines converging over twelve centuries — beginning in the Islamic world. Al-Kindi (801–873 CE), working in Baghdad, wrote the first known frequency analysis of language. He observed that certain Arabic letters appear far more often than others, and that this frequency pattern is consistent enough to decode encrypted messages. This is, mathematically, the same insight that makes modern automatic speech recognition work: human speech has statistical regularities that can be modeled.
Acoustics and Fourier (1822) — Any sound wave can be decomposed into simpler sine waves. This is the direct ancestor of the spectrogram used in every modern ASR system. Helmholtz established that human vowel sounds are produced by specific frequency combinations (formants). By 1939, Bell Labs' VOCODER was already separating speech into frequency bands.
Information theory (Shannon, 1948) — Language is statistically predictable. Shannon calculated English text redundancy at 75% — most of what we say is predictable from context. Al-Kindi's frequency analysis of Arabic letters was the first empirical demonstration of exactly this principle.
Hidden Markov Models (1970s) — The breakthrough that made practical ASR possible. HMMs treat acoustic signals and phonemes as a probabilistic chain. CMU's Harpy (1976) recognized 1,011 words. Dragon NaturallySpeaking (1990s) reached 98% accuracy at 100 wpm.
Deep learning (2010s) — OpenAI's Whisper (2022), trained on 680,000 hours of multilingual audio, brought near-human accuracy to 97 languages including Arabic and French. The Web Speech API on this page runs in Chrome: microphone → neural network → phonemes → language model → text. From al-Kindi's tables to this API spans 1,150 years of mathematics.
📖 Description & Examples
Description: Convert your voice into text in 10+ languages using your browser's speech recognition engine. Supports English, French, Spanish, German, Arabic, Chinese, Japanese, Portuguese, Russian, and more.
Recognition runs locally in your browser — ideal for fast dictation, notes, transcripts, or hands-free writing.

Tool 2 – Text to Speech (Read Aloud Voice Generator)
Synthetic Voice: From al-Jazari's Automata to WaveNet
Read more
Al-Jazari (1136–1206 CE) built automated musicians that performed without human intervention — the first documented attempt to mechanically replicate human musical performance. The science of synthesizing human-like output from mechanical systems begins here, not in 20th-century laboratories.
Homer Dudley's Voder (Bell Labs, 1939) let a trained operator produce intelligible English by manipulating keys. Audiences found it deeply unsettling. Early TTS systems (DECTalk 1983, SAPI 1995) were recognizable as machines. Google's WaveNet (2016), trained directly on raw audio waveforms, reduced the gap to near-imperceptibility. Text-to-speech is now a standard accessibility tool: listening to your own writing read aloud reveals rhythm problems and repeated words that the eye skips because it already knows the text.
📖 Description & Examples
Description: Convert any written text into synthetic speech. Choose a voice, set the speed, and click Play.
🌐 Arabic TTS: Works best in Microsoft Edge (Windows) — includes Arabic Neural voices. On Chrome/Firefox, install an Arabic language pack on your device.
Tool 3 – Speech to Translate to Speech (Voice Translator)
Translation: From the House of Wisdom to Neural Machine Translation
Read more
The Bayt al-Hikma (House of Wisdom) in Baghdad (8th–10th centuries CE) translated Greek, Persian and Indian scientific knowledge into Arabic. Without this project, Aristotle's logic, Euclid's geometry, Ptolemy's astronomy, and Galen's medicine would not have survived the collapse of Roman institutions.
Hunayn ibn Ishaq (809–873 CE) translated over 260 medical texts from Greek into Arabic, developing systematic translation methodology not replicated in European practice until centuries later. Machine translation: IBM+Georgetown 1954 (rules) → Google Translate 2006 (statistical) → Transformer 2017 (neural). Voice translation combines ASR, MT and TTS — each step multiplies errors. Hunayn ibn Ishaq understood this 1,200 years ago: you cannot translate a concept that has no equivalent in the target language.
📖 Description & Examples
Description: Speak in your language, get instant translation via MyMemory API, then listen to the translated result in the target language. Arabic output works via Microsoft Edge's built-in Neural voices, or requires an Arabic language pack on other browsers.

Dictation Workbench
Read more
Speech to text helps users move from spoken ideas to written drafts quickly. It is useful for notes, outlines, accessibility support and language practice when typing slows the thought down.
The best use is drafting, not blind publishing: users can dictate naturally, then edit the transcript for punctuation, names and specialist terms.
Voice Accessibility Panel
Read more
Text to speech makes written content easier to review, hear and understand. Voice translation adds another layer by helping users test meaning across languages in a practical way.
Together, these tools support students, travelers, creators and users who prefer listening or need an accessibility-friendly way to interact with text.
