Announcing the Multilingual Conversational Speech Language Model (MLC-SLM) Challenge

MONROVIA, Calif., March 19, 2025 /PRNewswire/ -- 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.
