摘要

•Presents a wristwatch/smartphone-based ECG, photoplethysmogram, and voice recorder.•ECG and photoplethysmogram signals are used to estimate pulse transit time (PTT).•Vowels are automatically detected in speech to extract spectral features.•PTT and speech features are used in a combined model to estimate blood pressure.•The cuffless system estimates blood pressure continuously with low processing load.
