schema_version: 1.0.0 report_type: speech-asr task_type: automatic-speech-recognition title: Whisper Medium INT8 description: >- INT8-quantized automatic speech recognition family for English speech-to-text, based on an encoder-decoder Transformer and optimized for efficient on-device use on ARM smartphones. It uses weight-only dynamic INT8 quantization with FP32 activations, LiteRT/TFLite execution, and KV-cache autoregressive decoding to reduce model size and improve transcription speed while preserving accuracy for clean English audio. id: Arm/whisper-medium-int8-litert filename: whisper-medium-int8-litert.tflite base_model_id: openai/whisper-medium vendor: OpenAI base_model_url: https://huggingface.co/openai/whisper-medium profile: Arm-Optimized optimization: optimized_by: Arm related_technologies: - SME2 weight_dtype: int8 quantization: method: PTQ-dynamic weight_bits: 8 activation_bits: 8 symmetric: true mode: dynamic weight_granularity: per-channel model_size_mb: 743.146 parameter_count: 763857920 format: litert
