Methods and systems directed to telephone number retrieval are provided. A terminal requests a telephone number from a telephone number service. A voice response comprising the telephone number is received from the telephone number service. A feature vector sequence is stored in memory of the terminal as a reference pattern for the received voice response. The voice response has designated words between and among numbers of the telephone number. A keyword spotting routine searches for the designated words. Connecting words, located between and among designated words, comprising the telephone number are extracted and stored in a buffer. A number recognizer analyzes contents of the buffer. The number recognizer outputs a recognized telephone number for display on a terminal and/or storage in memory for future use.
