    Time-Frequency Analysis for Voice Activity Detection

  • Original language description

    This paper introduces two different ways of time-frequency representations for voice activity detection (VAD). The first method is based on the chirp transformation of the signal, while the second method is based on wavelet decomposition. The performanceof both methods with clean speech and speech in noisy conditions is evaluated, and their limitations are discussed.

    Časově-kmitočtová analýza detekce hlasové aktivity

  • Czech description

    Příspěvek představuje dva různé způsoby časově-kmitočtové reprezentace pro detekci hlasové aktivity. První metoda je založena na chirpové transformaci signálu, zatímco druhá metoda využívá vlnkové dekompozice. Byla hodnocena účinnost obou metod pro čistou a zašuměnou řeč a distutována příslušná omezení.
