ASR Models

Batch Transcription

Model	Description
Parakeet TDT v3	25 European languages, 0.6B params. Default ASR model.
Parakeet TDT v2	English only, 0.6B params. Better English recall.

TDT models process audio in chunks (~15s with overlap). Fast enough for dictation-style workflows.

Streaming Transcription

Model	Description
Parakeet EOU	120M params. 160ms/320ms frames for real-time results with end-of-utterance detection.

Custom Vocabulary

Model	Description
Parakeet CTC 110M	CTC-based keyword spotting alongside TDT.
Parakeet CTC 0.6B	Larger CTC variant.

VAD Models

Model	Description
Silero VAD v6	Voice activity detection on 256ms windows.

Diarization Models

Model	Description
Pyannote CoreML Pipeline	Segmentation + WeSpeaker embeddings. Online and offline modes.
Sortformer	End-to-end streaming diarization. Single neural network, 4 speaker slots.

TTS Models

Model	Description
Kokoro TTS	82M params, 48 voices. Flow matching + Vocos vocoder. Requires espeak.
PocketTTS	155M params. Autoregressive, no espeak dependency.
