Project Overview:

Objective

We successfully built a comprehensive dataset of audio clips featuring the “Alexa” wake word, as articulated in Mexican Spanish by adults. This dataset is now a pivotal asset for enhancing wake word recognition systems and voice assistants, specifically designed for this demographic group.

Scope

Our team gathered an extensive array of audio recordings from adult Mexican Spanish speakers. These recordings, captured in various settings and accents, were meticulously annotated by us to include precise wake word annotations, showcasing our expertise in data annotation.
