In addition to performance, Jason Nedecky is increasingly sought after for his expertise in lyric diction. He coaches both voice students and professional singers in the pronunciation of English, German, Italian, and French texts. He has acted as a language coach at the Canadian Opera Company, the Luminato Festival, Société-Radio-Canada (for the overall winning entry of the 2012 International French Radio Competition), the Toronto Children’s Chorus, Opera NUOVA (Edmonton), the Mountain View Summer Festival (Calgary), and the Canadian Opera Company Summer Intensive Program. He is English diction specialist for The Diction Police website, offering advice for singers on pronunciation and accent shift in interviews and online phonetic readings.

Jason Nedecky is one of the leading diction experts of our time, in several languages. He understands the complexities, details, and nuances of lyric diction, and can explain them in terms that are easy for singers to understand.

Jason Nedecky teaches diction and repertoire courses at the University of Toronto Faculty of Music, and is language coach for its Opera Division. At the Glenn Gould School of the Royal Conservatory of Music, Toronto, he is instructor of French diction and repertoire courses.


Nedecky is the author of French Lyric Diction: A Singer’s Guide, published by Oxford University Press. This new book is the most comprehensive English-language resource on singing the French language in print. It treats all aspects of the language at is traditionally sung in opera and mélodie — including a detailed account of liaison in singing, rarer cases and exceptions, pronunciation options, conventions for loanwords and names, and obscure spellings — and gives pronunciation dictionaries of proper nouns and musical terms not found anywhere else.


A keen interest in French language and repertoire led to a recent extended stay in France. This afforded Nedecky the opportunity to coach with and observe the work of notable artists in the field of French vocal music, including baritone François Le Roux. Nedecky is also a contributor to the second edition of Le Roux’s Le chant intime.

Jason Nedecky is a passionate and extremely well-informed advocate of lyric diction. I’m happy to turn to him regularly while preparing French operas for his expert knowledge and collegiality.
