Abstract. This paper discuses preliminary results on acoustic models creation through acoustic models already in existence for another language. In this work we show as case of study, the creation of acoustic models for Mexican Spanish, tagging automatically the training corpus with a recognition system for French. The resulting set of acoustic models for Mexican Spanish has gathered promising results at the phonetic level, reaching a recognition rate of 71.81%.

“…Habitualmente, las transcripciones utilizadas solo se ciñen al nivel del fonema -salvo los trabajos de Llisterri y Mariño (1993) y Pineda, Villaseñor, Cuétara, Castellanos y López (2004), que llevan a cabo un estudio alofónico parcial-. Además, la práctica totalidad de los trabajos previos agrupa las vocales cerradas junto con sus respectivas variantes semiconsonantes y semivocales (esto es, las conocidas actualmente como 'paravocales').…”

RESUMEN:El cálculo de la frecuencia de aparición de los distintos fonemas de la lengua española es un asunto que se ha abordado previamente en varias ocasiones. Sin embargo, la gran mayoría de los estudios realizados no toma en consideración la variación alofónica o la trata solo parcialmente. Además, en todos estos trabajos los recuentos se han llevado a cabo a partir de palabras aisladas, sin tener en cuenta los fenómenos fonéticos que se producen en la secuencia fónica, especialmente el resilabeo.En el presente trabajo se realiza un recuento de los porcentajes de aparición de los distintos fonemas y alófonos en el dialecto castellano. Para ello, se ha creado un corpus de novelas en español, que se transcriben automáticamente con ayuda de un programa informático creado ex profeso, cuyo diseño se detalla en este artículo. También se realiza un estudio limitado de la estructura silábica en términos de frecuencias de aparición.Palabras clave: frecuencia de aparición; fonemas; alófonos; español; cadena hablada. ABSTRACT:Frequency of occurrence of phonemes and allophones in contemporary Spanish as calculated by an automatic transcription system.-The frequency of occurrence of the different phonemes of the Spanish language has been the subject of several previous studies. However, most of those studies did not take into account the frequency of the allophones, or they did it only partially (many times there was not even a phonetic transcription, and the plain orthographic transcription was used instead). Moreover, in all those previous works the frequency of occurrence was calculated from the transcription of isolated words, without taking into account the phonetic changes produced by its insertion in the speech chain, especially that of resyllabification.The present article calculates the frequency of occurrence of the phonemes and allophones of the Castilian Spanish dialect, as they are pronounced in the spoken language. The transcription of a corpus (consisting in 560 novels of modern Spanish writers) is done automatically thanks to a piece of software implemented for the purpose of this study. The article details the contents of the corpus as well as a detailed description of the design of the automatic transcriber. Finally, there is also a limited study of the syllable structure in terms of its type and frequency of occurrence.Keywords: frequency of occurrence; phonemes; allophones; Spanish; speech chain. • Por un lado, crear un transcriptor que calcule automáticamente la transcripción fonética estrecha de un corpus de español actual (en su forma ortográfica normativa).• Por otro, y como objetivo final, realizar un recuento estadístico de las apariciones de los distintos fonemas y alófonos, así como de las estructuras silábi-cas más frecuentes, del español, en su variante dialectal castellana, del centro-norte peninsular.El transcriptor fonético que se ha implementado tiene en cuenta los cambios fonéticos y alofónicos que se dan

“…English and Spanish corpuses were used to test the method: DIMEx100 [7] is a Spanish corpus with 6,000 phrases coming from 100 subjects, each recording 60 different phrases. They were sampling in mono mode with 16 bits at 44.1 KHz.…”
