A voice-activated inquire system to be used over the telephone network imposes severe constraints upon the speech recognition component: it must be able to accept input speech from untrained speakers, it must be robust against spurious words and extra-linguistic phenomena (environmental noises and telephone line noises) and it must deal with reduced bandwidth. This paper approaches these aspects in the HMM framework.
