Abstract: The present invention relates to a real-time voice recognition apparatus equipped with an application-specific integrated circuits (ASIC) chip and a smartphone, capable, by using one smartphone and one ASIC chip and without using a cloud computer, of assuring personal privacy, and, due to a short delay time, enabling real-time conversion of voice input signals into text for output. When one DRAM chip is optionally added to the real-time voice recognition apparatus, the number of neural network layers is increased thereby significantly improving accuracy of conversion of voice input signals into text.

Abstract: The present invention relates to a smartphone-based hearing aid which does not employ a separate power supply or digital signal processing device and instead has an analogue interface unit, configured with a single integrated circuit chip, connected between a plurality of microphones and a smartphone, thereby realizing a compact size, reducing the cost and enhancing the audio performance. Instead of employing a digital signal processing chip which is essentially used in the existing hearing aids or personal sound amplifiers, the smartphone-based hearing aid according to the present invention utilizes components such as a smartphone-embedded application processor (AP), RAM, digital-analogue converter, speaker and display and is therefore affordable.

Abstract: Disclosed is a hearing aid attached to a mobile electronic device. Elements forming the hearing aid are separated into a main hearing aid device and a sub-hearing aid device. The main hearing aid device is attached to the casing of a mobile electronic device and connected to the mobile electronic device through a wired cable, and the sub-hearing aid device is placed in an ear of a user. Other people rarely notice that a user uses the hearing aid because the main hearing aid device is mounted on the casing of a mobile electronic device. The hearing aid is supplied with power from the battery of the mobile electronic device, and has the same size as the casing of the mobile electronic device. Accordingly, a beamforming operation through a microphone array is possible, and use convenience and a level of satisfaction of the hearing aid can be improved.
