The harmonic structure of the speech spectrum is crucial for accurate pitch detection. This study presents a method for enhancing the harmonic structure, leading to robust pitch estimation. After analyzing the speech of four males and four females, the results clearly show that the improved harmonic structure ensures pitch estimation independent of traditional issues.
