Auditory feedback methods to improve the pronunciation of stops by German learners of French

The effect of manipulation of a speaker’s voice as well as exposure to a native speaker’s utterance was investigated regarding the pronunciation of stops by German learners of French. Three subject groups, a Control (CG), a Manipulation (MG), and a Native Speaker (NG) Group, were recorded on two subsequent days. The MG was presented with a manipulation of their voice on the second day and the NG listened to a native French speaker, while the CG did not receive any feedback. Results show that speakers of the MG and NG were able to extract useful information from the respective feedback and successfully adapted to it. Participants were able to reduce their voice onset time values, although speakers of the NG reduced it to a greater extent
