AB  - The Karaoke is one of large industries using audio & video in Asia. One of popular features for the vocal that is used by Karaoke users has been Echo/Reverb. In addition to Echo/Reverb, if vibrato is added to vocal signals, the vocal vibrato will deliver more confidence to karaoke singers and make the singers feel themselves as professional singers. In this paper, we present a real-time ‘Vocal Vibrato Effecter’ running under Windows PC which automatically adds a vibrato effect to the vocal input. The proposed technique exploits vocal energy level and temporal consistency of the pitch variation. The key novelty in this work is the combination of pitch detector and pitch shifter (vibrato). This effecter can be applied to consumer/commercial Karaoke systems to enhance a vocal signal.
