Pas de conseil

Pas de conseils ou feed back, c’est dommage, il s’agit juste d’enregistrer et écouter en temps réel sa voix

Response from developer

Merci d'avoir essayé l'application ! Le DAF (Delayed Auditory Feedback, ou retour auditif retardé) est une technique de thérapie de la parole bien précise : l'application vous renvoie volontairement votre voix avec un léger décalage, et ce décalage est lui-même le mécanisme thérapeutique. Il est principalement utilisé pour le bégaiement, les troubles de la fluidité, ainsi que les difficultés d'élocution liées à certaines pathologies comme la maladie de Parkinson. Ce n'est donc pas une application de coaching avec des conseils ou des astuces — le bénéfice vient du fait de parler tout en entendant ce retour retardé. Si vous souhaitez en savoir plus pour bien l'utiliser, n'hésitez pas à me contacter via l'e-mail de support dans l'application.

マイクが切れる

本日購入して使用しましたが、しばらくするとマイクが切れました。1から2分後です。練習に使いたいのでこれでは使えません。修正してください。

Response from developer

Life Saver

This app has been a life saver. I cannot recall the last time I have ever felt more confident going into meetings. Little to no stammering, only have to gather my thoughts before I speak. Thank you to whoever developed this app. I plug in one ear piece to listen during meetings.
