We line up with the definition of podcast proposed by Furtoso and Garcia (2011), according to which the tool is "the audio file itself, published and available for download, a digital audio file '", by such a definition be the closest to the current use of the podcast, once the student can come, too, producing it and make it available to the teacher’s feedback. We cover possible uses and potentials of the podcast today with regard to teaching Spanish: initially, raising electronic sites with proposals on which the tool is used as input and, subsequently, exploring how the student went on to become an author in the context of teaching-learning from changes and improvements of the tool usage over time. Keywords: podcasts, teaching and technology, additional languages.
