## Supported Languages
:::(Info) (Requirement:)
The set of languages available in Virtual Translator is determined by the intersection of the **Speech Recognition (SR)**, **Text-to-Speech (TTS)** and **Translation** capabilities used in the translation pipeline. A language can only be supported in VT if SR, TTS and translation services are available for that language.
:::

### Languages Supported by SESTEK SR & TTS
The following languages are natively supported through the combination of Sestek Speech Recognition, Sestek Text-to-Speech engines, therefore VT can be used:
 
| # | Language |
|---|----------|
| 1 | Arabic |
| 2 | Azerbaijani |
| 3 | English |
| 4 | French |
| 5 | German |
| 6 | Hindi |
| 7 | Japanese |
| 8 | Kurdish |
| 9 | Pashto |
| 10 | Persian |
| 11 | Russian |
| 12 | Spanish |
| 13 | Turkish |
| 14 | Ukrainian |
| 15 | Urdu |
 
* For the full list of SR-supported languages, see [SR – Supported Languages and Models](https://docs.knovvu.com/docs/sr-supported-languages-and-models).
* For the full list of TTS-supported languages, see [TTS – Supported Languages and Voices](https://docs.knovvu.com/docs/tts-supported-languages-and-voices).
 
### 3rd Party TTS Providers
Beyond the native SESTEK TTS engine, Virtual Translator can also leverage the following third-party TTS providers to extend language and voice coverage:
 
| Provider | Supported Languages |
|----------|-------------------------------|
| Microsoft Azure TTS | [Language and Voice Support for Azure Speech](https://learn.microsoft.com/en-us/azure/ai-services/speech-service/language-support?tabs=tts) |
| OpenAI TTS | [OpenAI Text-to-Speech – Supported Languages](https://developers.openai.com/api/docs/guides/text-to-speech/#supported-languages) |
| ElevenLabs TTS | [ElevenLabs – Supported Languages](https://elevenlabs.io/docs/overview/models#text-to-speech) |

:::(Info) ()
If a language is supported by [SESTEK SR](https://docs.knovvu.com/docs/sr-supported-languages-and-models){target=`_blank`} and the 3rd party TTS provider mentioned above, Virtual Translator can be used.

### Translation Engine
SESTEK Virtual Translator supports the following translation options:

| Engine | Description | Supported Languages |
|--------|-------------|-------------------------------|
| Google Translate | Cloud-based neural machine translation supporting 189+ languages. | [Google Cloud Translation – Language Support](https://cloud.google.com/translate/docs/languages) |
| LLM Translation (OpenAI) | Translation powered by large language models. Supports a broad and continuously expanding set of languages without a fixed list. | Any |
Both translation engines can be used interchangeably depending on deployment requirements, cost considerations, and language pair availability.
 
:::(Info) ()
Since OpenAI has no language limitation for translation functionality, any language supported by SR/TTS can be used VT.
