Parakeet-TDT-0.6B v3 (ANE)

Model Description

parakeet-tdt-0.6b-v3 is a 600M-parameter multilingual automatic speech recognition (ASR) model from NVIDIA. It extends parakeet-tdt-0.6b-v2 by moving beyond English-only to support 25 European languages with automatic language detection.

The model was primarily trained on the Granary multilingual corpus and is optimized for both research exploration and production deployment.

This build is integrated with nexaSDK and optimized for modern NPUs, including Apple’s Neural Engine (ANE), for efficient on-device inference.

Features

• Multilingual ASR: 25 European languages with built-in language detection.

• Text formatting: Outputs text with punctuation and capitalization.

• Timestamps: Provides both word-level and segment-level timestamps.

• Long audio transcription:

  • Up to 24 minutes with full attention (A100 80GB).
  • Up to 3 hours with local attention.

• Optimized for NPUs: Runs efficiently on Apple ANE, Qualcomm Hexagon, and other dedicated accelerators.

• Commercial-friendly: Released under CC-BY-4.0 license.

Apple Neural Engine (ANE)

The Apple Neural Engine (ANE) is a specialized NPU in Apple silicon designed to accelerate AI and ML workloads [3]. By offloading heavy ASR computations to the ANE, parakeet-tdt-0.6b-v3 achieves:

• Lower latency speech transcription on iPhone, iPad, and Mac.
• Energy-efficient inference, extending battery life during real-time ASR tasks.
• On-device privacy, keeping voice data local while maintaining production-grade accuracy.
