MONROVIA,Calif.,March 19,2025 -- Nexdata,a leading global provider of AI data services today announces the start of The Multilingual Conversational Speech LLM (MLC-SLM) Challenge,an officially approved satellite event of Interspeech 2025.

This challenge,hosted by Meta,Google,Samsung,Naver,China Mobile,Northwestern Polytechnical University and Nexdata,aims to advance multilingual conversational speech AI by providing a real-world dataset and encouraging innovation in speech language models.

The challenge consists of two tasks,both of which require participants to explore the development of speech language models (SLMs):

Task I: Multilingual Conversational Speech Recognition

Objective: Develop a multilingual LLM-based ASR model. Participants will be provided with oracle segmentation and speaker labels for each conversation.

Task II: Multilingual Conversational Speech Diarization and Recognition

Objective: Develop a system for both speaker diarization (identifying who is speaking when),and recognition (transcribing speech to text). No prior or oracle information will be provided during evaluation (e.g.,no pre-segmented utterances or speaker labels). Both pipeline-based and end-to-end systems are encouraged,providing flexibility in system design and implementation.

The training set (Train) comprises approximately 11 languages: English (en),French (fr),German (de),Italian (it),Portuguese (pt),Spanish (es),Japanese (jp),Korean (ko),Russian (ru),Thai (th),Vietnamese (vi). It's designed to provide a rich resource for training and evaluating multilingual conversational speech language models (MLC-SLM),addressing the challenges of linguistic diversity,speaker variability,and contextual understanding.
