“…Additional requirements may apply for voice activation systems. For example, responding only to a keyword that was addressed to the system, but not to the same keyword spoken in the conversation (wake-up-word detection) (Këpuska and Klein, 2009;Zhang et al, 2016); responding only to a keyword spoken by a registered user (Gruenstein et al, 2017;Manor and Greenberg, 2017;Kurniawati et al, 2012).…”

Improving the effectiveness of voice activation systems with machine learning methods

“…Additional requirements may apply for voice activation systems. For example, responding only to a keyword that was addressed to the system, but not to the same keyword spoken in the conversation (wake-up-word detection) (Këpuska and Klein, 2009;Siegert et al, 2021;Zhang et al, 2016); responding only to a keyword spoken by a registered user (Gruenstein et al, 2017;Kurniawati et al, 2012;Manor and Greenberg, 2017).…”

“…Some authors use completely different approaches to decoding. For example, Manor and Greenberg (2017) described an application of fuzzy logic to decoding.…”
