This correspondence describes an improved version of the linear prediction formant tracking algorithm which was described in . The new algorithm, like the original one, applies continuity constraints and branches out from an anchor point in the middle of each vowel. The changes are that the initial estimates for the formant frequencies at the anchor are determined more carefully, and that the option of choosing a new anchor point near the original one is allowed if the original one caused problems.
