We present the design and implementation of a swallowing-assisted device for disphagic patients in this paper. This device is capable of detecting a swallow signal in surface electromyography (SEMG) from a dysphagic patient, a person who has difficulty in swallowing. The sampling rate at 1000 samples/s was used in SEMG data acquisition. Each sample was collected with 16-bit resolution. Results from the real-time implementation on TMS320VC5509A demonstrate that the swallowing detection system based on the digital signal processor functions correctly. In other words, the trigger signal is appropriately generated for 1 second when the beginning point of swallowing signal is detected. When total number of swallows was 40, the system was able to detect 37 times of swallows correctly.
