TSL Langues is an editing and translation company founded and managed by Bénédicte Dazy.

Bénédicte Dazy holds a master's degree in Linguistics, which attests to her strong knowledge of the rules of French grammar and usage, and finished her training at the École Supérieure des Interprètes et des Traducteurs (ESIT) in Paris. She has an extensive background in editing and interpretation and has worked in this role for more than ten years; she has begun to do translation work as well.

Services offered


TSL Langues specializes in translating from English and Italian into French. The professional who will be entrusted with translating your text will be a native speaker of the language into which the text will be translated. This guarantees that the result will be natural and will reflect a mastery of the nuances of the language. We also take care to adapt the text to the spelling, punctuation, and typographic norms of the country where the work will be published, a detail that is very much appreciated by our clients.


However competent a translator might be, it is always necessary that a second pair of eyes look over the result and verify that it has been well prepared. At our company, this task is performed by a different translator--a native speaker of the source language--who verifies the translation's fidelity to the original. This reading, carried out by all good professional translators, is at other companies often billed at a higher rate than the price of the initial translation. At TSL Langues, there will be no such bad surprise: this important stage is included in this initial price.


It is customary to bill according to the number of words in your text. You can yourself verify this information using the "word count" feature in Microsoft Word.


In some cases, TSL Langues can undertake translations from French into English or Italian, provided that it is possible to guarantee that the quality of the translation will be irreproachable. For all requests, please contact us by email.

"J'apprécie particulièrement le respect dont TSL Langues fait preuve envers les auteurs. La correctrice possède cette qualité qui consiste à se fondre dans le style du texte qu'elle corrige pour lui donner de la hauteur à force de propositions et d'échanges avec l'auteur. Elle n'hésite pas à effectuer un travail de recherche d'informations pour s'adapter au thème des documents soumis et les corriger au mieux, preuve de son honnêteté intellectuelle." G. F. (Université Grenoble Alpes)
"Lorsque j'étais étudiante infirmière, j’avais toujours un compte-rendu, un mémoire, une analyse de pratique ou un résumé à rendre aux professeurs. Ayant quelques difficultés en français, j’ai toujours fait appel à TSL Langues. La correctrice est la meilleure et, grâce à ses conseils, je me suis améliorée et mes notes étaient bonnes. A la fin de mes études, c'est mon mémoire qui a reçu la meilleure note et c'est à elle que je le dois." L. E. Y. (Institut de formation en soins infirmiers, Clamart)
"TSL Langues mi ha tradotto, o corretto, molti articoli in francese. La traduttrice è molto brava, scrupolosa e attenta anche ai dettagli. La sua formazione di linguista le consente di valutare pienamente anche le sfumature grammaticali e di contenuto." P. A. (Historia et ius)
"Traduction sûre de l'italien vers le français. TSL Langues est entièrement fiable concernant les corrections de textes en français, qu'ils soient des premières esquisses ou des épreuves d'éditeur.

V. (Université de Lorraine)
