# Text to speech in 31 languages: one voice for every language Updated 2026-10-24 Supertonic 3, the open text-to-speech model behind SuperClonica, speaks 31 languages, and every voice in the catalog speaks all of them. A voice made from an English recording can read your text in Spanish, Hindi or Japanese, and a Russian narrator can voice the same video in German. This guide lists the supported languages, explains how to choose the language for a text, and gives tips for the most requested ones. Chinese is not supported yet. ## How one voice speaks 31 languages A voice in Supertonic 3 describes how someone sounds, not which language they speak. The language is chosen for each text with a language code, so the same voice file works for all 31 languages. The accent of the original recording can still be heard a little, which suits characters and is barely noticeable in narrators. Try it on the page of any voice: pick the language next to the text field, type a phrase of 30 to 100 characters and press Voice it. On your computer, the SuperClonica engine takes the code with --lang, for example superclonica --text "Hola, ¿qué tal?" --voice voice.json --lang es --output hola.wav. ## English text to speech Code en. English is the most common language of the catalog voices: narrators, game and film characters, announcers. Numbers, dates and units are read as words; write abbreviations the way they should be pronounced. ## Spanish text to speech Code es. Write accents and the opening ¿ and ¡ marks: they help the model with stress and intonation. Every voice can read Spanish, including characters recorded in English. ## Portuguese text to speech Code pt. Keep the diacritics (ã, ç, é) in the text. The model reads one Portuguese; Brazilian or European wording is up to your text. ## German text to speech Code de. Long compound words are read correctly as they are; write umlauts and ß, not ae or ss, for the best pronunciation. ## French text to speech Code fr. Keep accents and the apostrophes of elision (l’, d’, j’): they change how words are linked when spoken. ## Russian and Ukrainian text to speech Codes ru and uk. Write in Cyrillic. In Russian, write ё where it belongs; stress marks are not needed. Numbers are read as words in both languages. ## Japanese text to speech Code ja. Write in the usual mix of kanji and kana; for an unusual reading of a name, write it in kana. Japanese suits anime and game characters: many of them can say a line in the original language. ## Korean text to speech Code ko. Write in Hangul with normal spacing between words; the spacing helps the model with rhythm. ## Hindi text to speech Code hi. Write in Devanagari script: the model is made for it, while Hindi written in Latin letters may be read less accurately. Every voice in the catalog can read Hindi. ## Arabic text to speech Code ar. Write in Arabic script; vowel marks on ambiguous words may help the model choose the right reading. ## Turkish, Indonesian and Vietnamese text to speech Codes tr, id and vi. Keep the special letters and tone marks of each language (ç, ğ, ş, ı in Turkish; the tone marks in Vietnamese): without them words are read differently. ## Italian, Polish and other European languages Codes it, pl, nl, sv, da, fi, cs, sk, sl, hr, hu, ro, bg, el, et, lv and lt. Write each language with its own letters and diacritics; Greek and Bulgarian in their own alphabets. ## Numbers and dates in every language The SuperClonica engine spells numbers out as words in 27 of the 31 languages, so 2026 or 150 is read naturally. Grammatical cases are not added: where a language needs a special form, such as an ordinal, write it in words. The engine option numbers=False passes digits to the model as they are. ## More guides - [How to convert text to speech offline on your computer](https://superclonica.com/en/guides/offline-text-to-speech) - [Voice cloning: how to get a voice that sounds like a recording](https://superclonica.com/en/guides/voice-cloning) - [The best free text-to-speech models for local use in 2026](https://superclonica.com/en/guides/best-free-tts-models) - [Text to speech for videos, audiobooks, games and apps](https://superclonica.com/en/guides/text-to-speech-for-videos) - [Supertonic 3 voices: where to get custom voices and how to use them](https://superclonica.com/en/guides/supertonic-3-voices) - [Text to speech in Python: offline, free and with natural voices](https://superclonica.com/en/guides/python-text-to-speech) - [Self-hosted text-to-speech API in Docker](https://superclonica.com/en/guides/text-to-speech-api-docker) - [Text to speech in character voices: voice any line as your favourite character](https://superclonica.com/en/guides/character-voice-generator) - [Free unlimited text to speech without sign-up: run it on your own computer](https://superclonica.com/en/guides/free-unlimited-text-to-speech) - [Narrator voice generator: narration for videos, audiobooks and podcasts](https://superclonica.com/en/guides/narrator-voice-generator) - [Child voice text to speech: kid and teenager AI voices](https://superclonica.com/en/guides/child-voice-text-to-speech) - [Anime voice generator: text to speech in anime character voices](https://superclonica.com/en/guides/anime-voice-generator) - [Female voice text to speech: natural AI female voices](https://superclonica.com/en/guides/female-voice-text-to-speech) - [Male voice text to speech: deep and natural AI male voices](https://superclonica.com/en/guides/male-voice-text-to-speech) - [Realistic text to speech: AI voices that sound human](https://superclonica.com/en/guides/realistic-text-to-speech) - [AI voice generator: turn text into speech with ready AI voices](https://superclonica.com/en/guides/ai-voice-generator) - [Text to speech reader: listen to books, PDFs and articles](https://superclonica.com/en/guides/text-to-speech-reader) - [TikTok voice generator: voices for TikTok, Shorts and Reels](https://superclonica.com/en/guides/tiktok-voice-generator) - [Dota 2 hero voices: make any hero say your line](https://superclonica.com/en/guides/dota-2-voice-generator) - [Cartoon voice generator: make a cartoon character say your text](https://superclonica.com/en/guides/cartoon-voice-generator) - [Jarvis voice generator: your text in a Jarvis-style AI voice](https://superclonica.com/en/guides/jarvis-voice-generator) - [Darth Vader voice generator: Star Wars voices for your text](https://superclonica.com/en/guides/darth-vader-voice-generator) - [Train your own TTS voice on your NVIDIA GPU](https://superclonica.com/en/guides/train-tts-voice) - [Emotional text to speech: how to make an AI voice sound expressive](https://superclonica.com/en/guides/emotional-text-to-speech) - [Hindi text to speech: AI voices that read Hindi](https://superclonica.com/en/guides/hindi-text-to-speech) ## Text to speech and comparisons - [Text-to-speech that runs on your own computer](https://superclonica.com/en/text-to-speech) - [Supertonic vs SuperClonica: same model, faster and cleaner](https://superclonica.com/en/compare/supertonic) - [Fish Audio and Fish Speech vs SuperClonica](https://superclonica.com/en/compare/fish-audio) - [OmniVoice vs SuperClonica: more languages or more speed](https://superclonica.com/en/compare/omnivoice) - [Qwen3-TTS vs SuperClonica for local text-to-speech](https://superclonica.com/en/compare/qwen3-tts) - [VoxCPM 2 vs SuperClonica: studio sound or CPU speed](https://superclonica.com/en/compare/voxcpm) - [F5-TTS vs SuperClonica: zero-shot cloning or fast CPU speech](https://superclonica.com/en/compare/f5-tts) - [An offline alternative to ElevenLabs](https://superclonica.com/en/compare/elevenlabs) - [Kokoro TTS vs SuperClonica: two small models for local speech](https://superclonica.com/en/compare/kokoro) - [Piper TTS vs SuperClonica: tiny devices or custom voices](https://superclonica.com/en/compare/piper) - [Coqui XTTS-v2 vs SuperClonica: a Coqui TTS alternative](https://superclonica.com/en/compare/xtts) - [Chatterbox TTS vs SuperClonica: instant cloning or a trained voice file](https://superclonica.com/en/compare/chatterbox) ## Frequently asked questions ### Which languages does Supertonic 3 support?
