IPA Source--the database was developed to benefit singers, teachers, and all those interested in the correct and knowledgeable performance of vocal literature. What started in 2003 as a support site for students in a university diction class has grown into the largest collection of literal translations and International Phonetic Alphabet (IPA) transcriptions on the web. The goal of IPA Source is to promote the comprehension and accurate pronunciation of foreign language texts in art song and opera in order that the singer may imbue each syllable with the appropriate emotional content.
