Which one should you pick?
Pick Gladia if
You’re building around voice product developers. Gladia took Whisper and re-engineered it to work in production — sub-300ms streaming latency, code-switching across 100+ languages, diarization and translation in the same stream. For developers building voice products it's a serious Whisper-API upgrade.
Pick NVIDIA NeMo if
You’re building around ml engineers training custom asr, including parakeet and canary models.. NeMo is the toolkit behind Parakeet, currently near the top of Hugging Face's open ASR leaderboard. A heavy framework with PyTorch Lightning under the hood, suited to teams comfortable training their own models.

Frequently asked
What does Gladia do better than NVIDIA NeMo?
Gladia's standout is "Sub-300ms real-time latency". NVIDIA NeMo doesn't make that promise — it leans into "Reference models match commercial ASR quality" instead. If the first sentence describes your workflow, pick Gladia; if the second does, pick NVIDIA NeMo.
What are the trade-offs?
Gladia: api-only, no editor for end users. NVIDIA NeMo: steep ml engineering learning curve. Whether either matters depends entirely on what you actually need — neither is a deal-breaker by itself.
Can I use Gladia and NVIDIA NeMo together?
Both are transcription tools so most teams pick one. Some workflows do combine them — for example, using Gladia for one show or episode type and NVIDIA NeMo for another. Worth trying both free tiers before committing.
