- Abstract
Tools based on computational methods and techniques for automatic speech recognition are slowly being integrated in everyday life. One of their main advantages is allowing people to easily record text, using their own voice. Unfortunately, this technology is not perfect, and transcription errors are common. In Spanish, one of the most common errors is the omission of diacritical marks, since these techniques overlook stress. The recognition of the stressed syllable is vital in Spanish, since stress pattern is not fixed, as in other languages. This is to a great extent due to the fact that these techniques were developed originally for English, which lacks diacritical marks for stress, since it is not distinctive for word differentiation. Our proposal is to incorporate pitch analysis in automatic speech recognition techniques to improve writing of diacritical marks. Previous research has proven false the extended belief that the stressed syllable is always the loudest or most intense. Thus, intensity by itself is not the best indicator of the location of the stressed syllable in a word, i.e., the one that by graphic convention should carry a diacritical mark, and pitch should also be considered. Our research shows that pitch analysis helps to overcome this problem.
