A dual-model architecture enables proactive hearing assistants to automatically identify and isolate conversational partners from background noise in real-time on embedded devices. This system, anchored by the wearer's self-speech and conversational turn-taking, demonstrates robust speech separation (e.g., 14.62 dB SISDRi improvement over baseline) and high partner identification accuracy (96.8%) across diverse and noisy environments.
Key insights
- A dual-model architecture effectively balances the need for real-time, low-latency processing on embedded devices with the computational demands of capturing long-range conversational context.
- Self-speech serves as a robust and reliable egocentric anchor for distinguishing desired conversation partners from other speakers and background noise.
- Conversational turn-taking dynamics provide generalizable cues, enabling the system to adapt to various speakers, numbers of participants, languages, and noisy conditions without explicit language or speaker ID training.
