Brain-to-Language Decoding: Tasks, Signals, Methods, Evaluation, Practical Use and BeyondNew

This paper surveys brain-to-language decoding methods that translate neural activity associated with language production, internal speech, and perception into linguistic outputs. It reviews advances in neural recording technologies and representation learning approaches, covering recognition, acoustic reconstruction, and text generation techniques. The work discusses applications in restoring communication for patients with speech loss and understanding brain language representations.
