A large speech model vs a small one
A large speech model vs a small one: a balanced comparison for Azerbaijani business, grounded in how Chinar works.
High-Precision Azerbaijani Automatic Speech Recognition
Selecting a speech-to-text solution for Azerbaijani business requires a choice between generic global services and specialized local models. Many global speech services struggle with linguistic precision, often returning fluent, confident text in Turkish that may appear correct to non-speakers but is fundamentally inaccurate. In head-to-head tests of major 2026 speech services, both commercial and open-source options produced effectively unusable output because they lacked native support for the Azerbaijani language. To solve this, we provide ASR models built specifically for Azerbaijani rather than adapted from related languages. By training on genuine call-center recordings—including background noise, interruptions, and overlapping speech—these models outperform generic cloud alternatives. This approach ensures that businesses can achieve high word accuracy on real-world phone audio, moving beyond the limitations of models trained only on clear, read speech.
Advantages of Specialized Azerbaijani ASR
Eliminates 'Turkish-substitution' errors where global services return Turkish text instead of Azerbaijani
Superior accuracy on real-world phone audio, with the production model making 23% fewer word errors than a commercial cloud speech service
Complete data sovereignty and security, as all audio remains on your own infrastructure with no third-party retention
Significant cost reduction by eliminating per-minute cloud billing, making 100% call coverage affordable for QA and audits
High-speed processing performance, running four to seven times faster than benchmarked cloud speech services
Flexible deployment options across CPU and GPU hardware to match specific infrastructure constraints
Optimized Model Tiers for Every Use Case
Chinar-F: High-Volume Production
A compact transducer trained on real Azerbaijani call-center recordings. As the default production model, it is the most accurate for real calls, achieving 91% word accuracy on clear speech and 23% fewer errors than a commercial cloud speech service.
Chinar-L: Document-Ready Transcripts
Optimized for interviews and meetings, this GPU-based model produces professional transcripts with punctuation, capitals, and digits. It achieves 93–94% word accuracy on clear Azerbaijani speech, measured against human-checked transcripts.
Chinar-P: Minimal Infrastructure
A lightweight model requiring no GPU that runs 26x faster than real-time on four CPU cores. It provides punctuation and capitalization while remaining on a par with a commercial cloud speech service.
Implementing Localized ASR
Frequently Asked Questions
How do global speech services typically handle Azerbaijani?
Many global services either lack support for the language entirely or return fluent Turkish text. Because the languages are related, these transcripts can look correct to those unfamiliar with Azerbaijani while being inaccurate.
Can these models handle low-quality or noisy phone recordings?
Yes. Unlike models trained on read speech, these are trained on genuine call-center audio, meaning they are designed to handle background noise, overlapping speech, and standard phone-line quality.
Is it possible to test the technology before deployment?
Yes, visitors can test hosted ASR models for free at chinar.allmaz.az. You can upload a recording and get an editable Azerbaijani transcript without needing an account or credit card.
What are the infrastructure requirements for these models?
Requirements vary by model: Chinar-P runs on CPU only, Chinar-F runs on either CPU or GPU, and Chinar-L requires a GPU for its high-fidelity document formatting.
Does the system support other languages or mixed speech?
Currently, the models are optimized for Azerbaijani. However, support for Russian and mixed Azerbaijani–Russian speech is currently in development.
