Abstract

Through proliferation on smartphones and smart speakers, intel- ligent personal assistants (IPAs) have made speech a common in- teraction modality. Yet, due to linguistic coverage and varying lev- els of functionality, many speakers engage with IPAs using a non- native language. This may impact the...
