Broad Multilingual Reference
Whisper
Decide whether to run large-v3 or Turbo yourself for broad multilingual transcription. Compare operational tradeoffs against commercial APIs before building.
Self-Hosted Whisper vs APIBuild Versus Buy
Self‑Hosted Speech‑to‑Text vs API
Choosing between operating your own speech model and using a managed API balances operational control against hardware and engineering costs. Compare each model guide below to evaluate deployment complexity and resource requirements for your workload.
Featured Open-Weight Speech Models
Native Word Timestamps
Parakeet TDT 0.6B
Evaluate running Parakeet TDT-0.6B-v3 for 25 European languages with native word timestamps. Discover when in-house hosting beats commercial speech services.
Self-Hosted Parakeet vs APIEuropean Speech Translation
Canary 1B
Weigh hosting Canary-1B-v2 for European transcription and English translation against managed APIs. Understand language configuration needs before building your pipeline.
Self-Hosted NVIDIA Canary vs APIMultilingual Dialect Coverage
Qwen3 ASR
Assess hosting Qwen3-ASR 0.6B or 1.7B for 30 languages and 22 Chinese dialects. Check optional aligner requirements before replacing commercial providers.
Self-Hosted Qwen3-ASR vs APIWhat You Need to Run in Production
Job Queues, Retries, and Callbacks
Production speech services require resilient job queues, retry mechanisms with idempotency keys, and webhook callbacks to handle network failures, decoding timeouts, and traffic spikes.
Output Formats and Storage Deletion
Pipelines must parse raw model outputs into structured formats like JSON, SRT, and VTT while managing data retention policies and immediate storage deletion for sensitive recordings.
Model Upgrades and Evaluation Ownership
Teams own testing and benchmarking new model checkpoints, validating regression risks against silent or noisy audio, and managing runtime dependencies across driver updates.
Compute Sizing and Pipeline Orchestration
Self-hosting demands provisioning GPU capacity to balance concurrency against idle costs, decoding audio formats, and handling optional alignment or speaker separation stages.
