Application
As a cost-effective voice interface solution for smart devices, not only may it be necessary for Automated Speech Recognition (ASR) applications, but it could also be used for voice calls (Communication); it is particularly optimized for ASR front-end processing, greatly improving performance in voice interrupt and recognition capabilities. Given its comprehensive features, the following or similar smart devices are recommended for its application:
-
Navigation robots (ASR)
-
Medical equipment (ASR)
-
Fitness equipment (ASR)
-
Large-screen advertising machines (ASR)
-
Lecture streaming (Comms)
-
Camera microphones (Comms)
-
Smart speakers (ASR)
-
Conference treasure (comms)
