We present here a system that builds up a phonetic string from speech at its input. The front-end system has been designed in terms of low cost computation for easy real time implementation, easy and automatic speaker enrollment and low use of linguistic knowledge. It is compared with Olivetti's phonetic string build up system adapted for Spanish in ESPRIT Polyglot project, showing that it is competitive in terms of computation and recognition performance.
