Abstract
Viene proposto un circuito per il riconoscimento del parlato veloce e per tuttavia dai risultati accurati.Il riconoscimento del parlato consiste nell'estrarre sequenze di vettori da un segnale di parlato e nel confrontarli poi con vettori di riferimento corrispondenti alle parole da riconoscere, generalmente memorizzati in memorie a semiconduttore.Essendo spesso richiesto un riconoscimento in tempo reale il principale fattore limitante tali sistemi è il tempo di accesso alla memoria.Utilizzando invece delle consuete RAM dinamiche (DRAM) delle video RAM o memorie con architettura analoga, cioè dotate di porte indipendenti per l'ingresso e l'uscita e con uscite seriali ad alta velocità, l'architettura che ne risulta è priva di tempi di attesa.
