Legal Notice


IPA Source is a library database intended as a support resource in foreign language diction classes and class and private voice lessons. For those who do not have access to this resource through their school library, the database is available to individuals through single sales and subscription access.


In accordance with tax law, IPA Source does not collect state sales tax on purchases originating in states where we do not have Economic Nexus and / or remote seller Notice and Reporting requirements. If sales tax has not been added at the time of purchase, you may still be liable for state sales tax in the form of a Use Tax to be reported on your personal state income tax form; please consult your state tax laws for further information. Since IPA Source provides a purely digital product to be accessed directly from our website, the purchaser’s state of origin is their billing address.

IPA Source, LLC is committed to making our website and texts accessible to all. While our user base is global, we focus on the U.S. accessibility guidelines of the Americans With Disabilities Act.

As part of this effort, the IPA Source site adheres to the most recent HTML, CSS, JavaScript, and Java coding standards and practices. Our texts are provided in Adobe Acrobat format, using the latest available version of the software.

The purpose of our site and service is to promote the comprehension and accurate pronunciation of foreign language texts in art song and opera through the use of the International Phonetic Alphabet (IPA), a strictly visual phonetic representation of sound. This visual rendering is presented through the use of the Sil Sophia IPA9 font for which there is no screen reader equivalent. Furthermore, in addition to the IPA font, all our PDF files contain multiple languages (the original language of the text with English translations). Since PDF norms allow only one reading language to be set, even with proper tagging our PDF files remain unsuitable for the visually impaired.

At IPA Source we believe the best practice in learning pronunciation for the visually impaired is through listening and imitation of the sound. Since sound recordings of texts is not the purpose of our site, we offer our visually impaired subscribers help finding single language, reader-compatible copies of the texts contained in this site upon request.

The information gathered through the above processes is combined into a single Voluntary Product Accessibility Template (VPAT). This VPAT lists where a product complies, partially complies, or does not comply with accessibility guidelines. Request our VPAT by contacting us here.

The input of the original language texts comes from internet sources, printed texts, and vocal scores. The IPA transcriptions are original to the site and follow the guidelines set forth in Diction Help. In some cases, outside resources have been consulted for poetic clarification in the creation of the word-for-word and poetic translations, but, ultimately, all translations are original.
