A non-native speech database is a speech database of non-native pronunciations of English. Such databases are essential for the ongoing development of multilingual automatic speech recognition systems, text to speech systems, pronunciation trainers or even fully featured second language learning systems. Because of the comparably small size of the databases, however, many of them are not available through the common distributors of speech databases. This leads to the fact that it is hard for researchers in speech recognition to keep an overview of what kind of databases have already been collected, and for what purposes there are still no collections.
This article is based on a paper from the ASRU speech conference. The paper wanted to provide a useful resource regarding the issue above. This online article is intended to provide a place where information about non-native speech databases can be updated continuously by the speech research community.

Famous quotes containing the word speech:
“When toddlers are unable to speak about urgent matters, they must resort to crying or screaming. This happens even with adults. The voice is the carrier of emotion, and when speech fails us, we need to cry out in whatever form we can to convey our meaning. Often, what passes for negativism is really the toddler’s desperate effort to make herself understood.”
—Alicia F. Lieberman (20th century)
