“Gowajee” — a Thai Speech-Recognition AI from Chula

An engineering professor from Chula has designed “Gowajee”, a Thai-language speech recognition AI capable of delivering speech-to-text/ text-to-speech with the accuracy of a native speaker while keeping users’ data secure. Having been rolled out in call centers, and depression patients screening process, Gowajee is set to be adapted to many other functions.

Compact Speaker Systems Direct Sound Efficiently

In JASA Express Letters, researchers developed three designs for compact speaker systems that control the direction of sound more efficiently than previous models. For each speaker, the scientists were able to manipulate the timing and strength of the outgoing sound waves. They combined multiple speakers together into an array and used the constructive and destructive interference of sound waves to their advantage.
