Granite Speech 5.0: Transcribe, Translate, and Attribute more Accurately and Faster

IBM released granite-speech-5.0-2b, a new speech-language model trained on 390,000 hours of public audio that transcribes English, French, German, Spanish, Portuguese, and Japanese, translates to and from English in those languages plus English to Italian and Mandarin, and supports language-ID prompting and keyword lists up to 2,000 terms. It also updated granite-speech-5.0-470m-turboctc, which adds multilingual transcription and native punctuation and capitalization and reaches 19,870 RTFx on the Open ASR Leaderboard (about 1.6x faster than at launch), and granite-speech-4.1-2b-plus, which cuts word diarization error rate and speaker-attributed WER by 7% each and long-form WER by 24%. All three ship under Apache 2.0 with support in Transformers, vLLM, llama.cpp, and mlx-audio.
