This paper aims to highlight the production of /t ̪͡ ɾ/ allophonic group in Santiago de Chile in order to provide acoustic characteristics of the rotics. For this we created an elicitation task protocol (picture-naming game). Prosodic parameters were not analyzed and speech rate was not controlled during the experimentation. Results showed different realizations of the cluster (such as [t ə ɾ̞ ] [t ̪͡ ɹ ̝ ] or [ɹ ̝ ]) as well as a central vocalic intrusion [ ə ] in the non-affricated and non-fricative productions. This insertion seems to prevent coarticulation effects between /t / and /ɾ/ coronal consonants. Furthermore, we think that the vocoïde may play a role in the cluster's perception in particular of the following apico-alveolar tap stop. Data shows that [t ̪͡ ɹ ̝ ] and [ɹ ̝ ] are not motivated by linguistic factors but rather by sociolinguistic factors as age or socioeconomic profile.
