Fast start

Dependencies

System requirements to run python examples on x86-64 systems:

• python 3.8+;
• 1G+ RAM;
• A modern CPU with AVX, AVX2, AVX-512 or AMX instruction sets.

Dependencies:

• torch>=1.12.0;

Using pip: pip install silero-stress

from silero_stress import load_accentor
accentor = load_accentor()
sample_sent = "Меня зовут Лева Королев. Я из готов. И я уже готов открыть все ваши замки любой сложности!"
print(accentor(sample_sent))

Using torch.hub:

import torch
torch.set_num_threads(1)

accentor = torch.hub.load(repo_or_dir='snakers4/silero-stress)
sample_sent = "Меня зовут Лева Королев. Я из готов. И я уже готов открыть все ваши замки любой сложности!"
print(accentor(sample_sent))

Key Features

• Wide coverage

  Silero Stress covers ~4M known Russian words and word forms with 100% accuracy. It also covers ~2K homographs with F1 score of 0.85, per-word accuracy of 91% and total dataset accuracy of 93%.

• Fast

  On 1 CPU thread every ordinary word takes ~0.5ms to process, every 400-char sentence with two homographs (common prod case) takes ~30ms.

• Lightweight and portable

  Total package is about 50MB in size, boasting ~400x compression ratio.

• General and generalizable

  Silero Stress was trained on a large dataset, containing ~4M known words and word forms and ~120M annotated sentences with homographs. It also works with unknown (and invented) words with 60-70% accuracy.

• No Strings Attached

  Published under permissive license (MIT) Silero Stress has zero strings attached - no telemetry, no keys, no registration, no built-in expiration, no keys or vendor lock.

• Minimal and minified

  Code bloat, unnecessary dependencies and libraries are removed. Silero Stress depends only on PyTorch as a neural engine and the Python standard library.

Typical Use Cases

• Academic research
• Text-to-speech applications
• Telephony and call-center automation, voice bots
