Abstract
Este artículo presenta el procedimiento
establecido por el laboratorio de Acústica Forense
de la Comisaría General de Policía Científica
para la práctica de Ruedas de Reconocimiento de
Voz (RRV). Esta técnica es utilizada en aquellos
hechos delictivos en los que la víctima o testigo
no pudo ver el rostro del sujeto agresor pero sí
tiene el recuerdo de su voz. Se trata de una tarea
de discriminación perceptivo-auditiva cuya finalidad
es la asociación de estímulos de habla que
la víctima o testigo evoca de su memoria a corto
plazo con otros del supuesto agresor/a obtenidos
mediante una grabación. En dicha tarea también
se incluyen registros de voz de otros sujetos de la
misma comunidad lingüística y similar característica
vocal (timbre, tono, plano expresivo, etc.)
que el locutor investigado.
This lecture introduces the procedure followed by the Forensic Acoustics Laboratory of the Spanish Scientific Police for the practice of recognition skills using voice line-ups. This procedure is used in those criminal acts in which the victim or witness could not see the face of the aggressor but has the memory of his/her speech. It is a job of aural perceptual discrimination whose purpose is the association of speech stimuli that the victim or witness elicits from his or her short-term memory with others of the presumed aggressor obtained through a recording. This task also involves voice recordings of other subjects of the same linguistic community and similar vocal characteristics (timbre, tone, manner of speaking, etc.) as the speaker under investigation.
