Speech-to-Text
Transcribe and understand audio with AI
Speech-to-text-modellen voor transcriptie, meetings en zoeken
Speech-to-text (STT) modellen zetten gesproken audio om in geschreven tekst. De categorie dekt van podcasttranscripts tot realtime captioning-pipelines en spraakopdracht-interfaces in mobiele apps. Je grijpt naar STT wanneer je binnen audio moet zoeken, dictatie wilt bouwen, meetings wilt samenvatten of captions wilt genereren voor toegankelijkheid.

Incredibly Fast Whisper
Whisper Large v3 wrapped with Hugging Face Transformers optimizations (batched inference, flash attention) for very high throughput. Transcribes hours of audio in minutes on a single GPU. Maintained by Vaibhav Srivastav. Good when you need bulk transcription fast.
Whisper
OpenAI's Whisper running on Replicate. General-purpose speech recognition trained on 680k hours of multilingual audio. Transcribes and translates 99 languages, robust to accents and background noise, and outputs plain text, segments, or word-level timestamps.
Whisper Large V3
OpenAI's Whisper model. State-of-the-art speech recognition supporting 99+ languages.
Whisper Large v3 Turbo
OpenAI's distilled Whisper Large v3. ~216x realtime, 99+ languages, MIT-licensed weights.
Deepgram Nova-3
Deepgram's flagship STT. First to offer realtime multilingual transcription with self-serve customization.
SeamlessM4T
Meta's SeamlessM4T multimodal translation model. Takes speech or text input and produces transcription or translation across about 100 languages, including speech-to-text and speech-to-speech. One model covers ASR plus cross-lingual translation without chaining separate systems.
SeamlessM4T v2 Large (Speech)
Meta SeamlessM4T v2 Large speech mode. Speech-to-speech, speech-to-text, and text-to-speech translation across 100+ languages in a single unified model.
Whisper Diarization
Whisper Large v3 Turbo combined with pyannote 4.0 for speaker diarization, returning who-said-what segments with timestamps. Built by Thomas Mol. Returns a clean JSON of speaker-labeled segments, handy for meeting notes, interviews, and podcasts.
WhisperX
WhisperX (Large v3) with forced alignment for accurate word-level timestamps plus optional speaker diarization. Uses VAD to cut long files into segments and a wav2vec2 aligner to pin each word to its exact time. Useful for subtitles and per-speaker transcripts.

Learn moreDe prijs is bijna altijd per minuut audio. Flagship-modellen (Whisper Large V3, Deepgram Nova-3, ElevenLabs Scribe) kosten ongeveer €0,005-€0,015 per minuut. Een transcript van een podcast van een uur kost €0,30-€0,90 afhankelijk van de tier. Sommige providers rekenen extra voor premiumfuncties zoals sprekerdiarisatie, timestamps op woordniveau, samenvattingen of vertaling, dus reken het door met de functies die je daadwerkelijk inschakelt.
De afweging is nauwkeurigheid, latency en functieomvang. Whisper Large V3 leidt op ruw word-error-rate in benchmarkevaluaties en is open-weights, dus self-hostbaar. Deepgram Nova-3 en AssemblyAI Universal leiden op streaming-latency (sub-300ms eerste token) en kwaliteit van diarisatie. ElevenLabs Scribe leidt op meertalige dekking en code-switching (wanneer sprekers midden in een zin van taal wisselen). Voor batchtranscriptie wint Whisper meestal op de combinatie kosten-en-nauwkeurigheid. Voor realtime gesprekstranscriptie wint een streaming-first provider.
Pas op met ruisaudio: de word-error-rate verdubbelt ruwweg onder 20 dB SNR op elk model, en overlappende sprekers degraderen diarisatie zelfs bij flagships. Pre-process met een ruisonderdrukkingsmodel (RNNoise, Krisp) als je bron onvoorspelbaar is. Pas ook op met eigennamen: elk model transcribeert nog altijd ongebruikelijke namen, technische termen en merknamen verkeerd. De meeste providers accepteren een `keywords`-hintlijst om de decoder bij te sturen — gebruik die.
De topkeuzes hierboven dekken het nauwkeurigste model, het goedkoopste werkpaard, de optie die de langste audio ondersteunt en de snelste streaming-optie.
