Communication remains a major challenge for hearing- and speech-impaired individuals, particularly when interacting with people who are unfamiliar with sign language. This communication gap often leads to social isolation, dependence on interpreters, and serious difficulties during emergency situations where immediate assistance is required. Although several assistive technologies have been proposed, many existing solutions are either expensive, complex to use, or limited to one-way communication. This paper presents a Smart Glove for Gesture-Based Voice Assistance and Emergency Alerts, designed as a wearable, low-cost, and real-time assistive device. The proposed system uses flex sensors and an inertial measurement unit (IMU) embedded within a glove to capture hand gestures accurately. These gestures are processed by a microcontroller to identify predefined sign language patterns, which are then converted into audible speech using a voice output module. To enable complete two-way communication, a speech-to-text mechanism is integrated, allowing spoken words from non-sign language users to be converted into readable text and displayed on a screen for the hearing-impaired user.In addition to communication support, the system incorporates an emergency alert feature to enhance user safety. An SOS button or predefined emergency gesture triggers an alert message along with real-time location information using GSM and GPS modules.
