Gladia
A concise guide that compares leading open-source automatic speech recognition (ASR) frameworks and models, focusing on accuracy, deployment trade-offs, and enterprise readiness.

This article reviews major open-source ASR solutions — including Whisper, DeepSpeech, Kaldi, Wav2vec, and SpeechBrain — and summarizes each project’s technical strengths and typical use cases for organizations.

It highlights practical trade-offs: Whisper’s strong out-of-the-box accuracy but research-oriented limitations, Wav2vec’s self-supervised advantages for low-resource languages, Kaldi’s modular toolkit approach, DeepSpeech’s retrainability with shorter-recording constraints, and SpeechBrain’s broad, community-driven ecosystem for conversational AI.

Finally, the piece covers deployment considerations such as compute and engineering costs, missing enterprise features (diarization, word-level timestamps, guardrails), and why hybrid or API-based solutions can offer lower total cost of ownership and faster time-to-production for many companies.
