Silero Models

Our TTS models satisfy the following criteria:

• Fully end-to-end;
• Large library of voices;
• Natural-sounding speech;
• One-line usage, minimal, portable;
• Impressively fast on CPU and GPU;
• For the Russian language - automated stress and homographs;

Installation and Basics

You can basically use our models in 3 flavours:

• Via PyTorch Hub: torch.hub.load();
• Via pip: pip install silero and then from silero import silero_tts;
• Via caching the required models and utils manually and modifying if necessary;

Models are downloaded on demand both by pip and PyTorch Hub. If you need caching, do it manually or via invoking a necessary model once (it will be downloaded to a cache folder). Please see these docs for more information.

PyTorch Hub and pip package are based on the same code. All of the torch.hub.load examples can be used with the pip package via this basic change:

from silero import silero_tts
model, example_text = silero_tts(language='ru',
                                 speaker='v5_ru')
audio = model.apply_tts(text=example_text)

Models and Speakers

All of the provided models are listed in the models.yml file. Any metadata and newer versions will be added there.

V5

V5 models support SSML. Also see Colab examples for main SSML tag usage.

Russian-only models support automated stress and homographs. v5_2_ru cointains minor fixes and removes numpy and scipy dependencies.

v5_3_ru cointains minor fixes. v5_4_ru also supports questions.

V5 CIS Base Models

• All of the below models support 8000, 24000, 48000 sampling rates and contain no auto-stress or homographs;
• v5_cis_base models assume that proper stress should be added for each word for all languages, i.e. к+ошка;
• v5_cis_base_nostress models assume that proper stress should be added for each word ONLY for slavic languages (i.e. ru, bel, ukr);
• All of the below models are published under MIT licence;
• V5 UTMOS and throughput metrics;
• V5 models support SSML. Also see Colab examples for main SSML tag usage;
• Use cases for the model;
• Minimal system requirements: a PyTorch-compatible system, a modern processor with AVX2 instruction set for x86/64 platform.

Supported alphabets

Please note that Georgian and Armenian are in fact internally supported via direct translation into cyrillic script inside of the package. Azerbaijani and Uzbek support both alphabets (Cyrillic and Latin).
