This work is part of the sound acquisition area in second language (L2), specifically in English, and it aimed to investigate whether there was a relationship between production and perception of the voiceless interdental fricative pronunciation [θ] or not in a group of Brazilian native speakers (BNS), based on acoustic and phonetic analysis. It was stated that there is such a relationship on account of the BNS in the sample. According to the literature, Brazilian learners of English tend to produce the voiceless interdental fricative [θ] as [s], [f] and [t] ((LIEFF & NUNES, 1993). This is because they consider such sound to be similar to [s], [f] and [t], and as stated by Flege (1999) and Meador, Flege and MacKay (2000), similar sounds of L1 (native language, in this case, Brazilian Portuguese - BP) and L2 may cause difficulties for the learner. Three studies have been made: an analysis of the production of the 3 BNS as well as of the AMS (American Native speaker) concerning the sound [θ]; an analysis of the perception of the sound [θ] by the 3 BNS and, finally, an evaluation of the 3 BNS productions of the sound [θ] by 31 American Native judges. The results of the three analyses have been crossed, and it can be posed that they conform to the literature about the link between production and perception and the assimilation of sounds from L2 to L1. Moreover, with such results, it was possible to achieve the goal of this work. It was verified that, regarding the perception analysis, the three BNS tend to perceive the sound [θ] as [θ] or [t]. Regarding the production analysis, one of the BNS approached the ANS. Therefore, it can be stated that there is a relationship between this BNS perception and production. The two remaining BNS did not approach the ANS. Most of the time, those speakers perceived the sound [θ] as [t], and the same happened with their productions of the sound [θ]. Taking into account those figures, it can be stated that there is a relationship among their production and perception, even if they have not perceived the sound [θ] as it should have been done. The perception and production analyses results were compared with the evaluation of the 31 judges, and the same can be said concerning all BNS: one of the BNS approached the ANS concerning the sound [θ], and the two remaining ones did not approach the ANS. To sum up, it was observed that, in this particular sample, there is a relationship between their production and perception, and that two out of the three BNS assimilated the sound [θ] as [t]
