Non-Verbal Cues

Non-Verbal Cues

Non-verbal communication extends beyond gestures and facial expressions to include vocal elements known as paralanguage. Paralanguage consists of non-verbal vocal cues such as pitch, loudness, speech rate, pauses, and non-verbal vocalizations like laughter, sighs, and moans. These elements not only accompany speech but also provide critical emotional and contextual information.The Role of Paralanguage in CommunicationParalanguage adds depth to spoken language by conveying emotions and...

This study introduces a novel audiovisual array system to enhance hearing aid performance in noisy environments. The portable, low-cost device uses a smartphone to improve speech intelligibility for users in challenging acoustic settings.

Area of Science:

Audiology
Signal Processing
Human-Computer Interaction

Background:

Hearing aids struggle in reverberant environments with high speech babble noise.
Existing assistive listening devices have limitations in complex acoustic scenarios.

Purpose of the Study:

To develop an affordable and portable audiovisual array system for hearing aid users.
To improve speech intelligibility in challenging noisy and reverberant conditions.

Main Methods:

A system combining a smartphone, a multi-microphone accessory, and software was conceptualized.
Real-time face detection and audiovisual beamforming algorithms were employed.
A PC-based experimental system was developed to validate the concept.
