Il existe aux US un Skill pour recevoir des notification via Alexa,
je leur ai posé la question d'un update en français, mais la réponse est sans appel:
Une bonne âme pour développer un skill en français.Thanks for your interest in Notify Me.
Unfortunately, we lack the resources to translate the skill to other languages. As you might know, we don't make any money for developing or maintaining the skill. Even if all the text was translated for us, someone would have to insert the translations into the code, test the results, manage it through the submission process, and then pay for the additional server usage while also providing ongoing support.
As a result, Notify Me is only available in the countries that allow English-speaking skills. Perhaps a local Alexa developer can be convinced to make an equivalent skill for your region?
Sorry we don't have better news.
