  • Title: Spectral modulation detection and vowel and consonant identifications in cochlear implant listeners.
    Author: Saoji AA, Litvak L, Spahr AJ, Eddins DA.
    Journal: J Acoust Soc Am; 2009 Sep; 126(3):955-8. PubMed ID: 19739707.
    Abstract:
    Speech understanding by cochlear implant listeners may be limited by their ability to perceive complex spectral envelopes. Here, spectral envelope perception was characterized by spectral modulation transfer functions in which modulation detection thresholds became poorer with increasing spectral modulation frequency (SMF). Thresholds at low SMFs, less likely to be influenced by spectral resolution, were correlated with vowel and consonant identifications [Litvak, L. M. et al. (2008). J. Acoust. Soc. Am. 122, 982-991] for the same listeners; while thresholds at higher SMFs, more likely to be affected by spectral resolution, were not. Results indicate that the perception of broadly spaced spectral features is important for speech perception.
