Voice and speech range profiles and Voice Handicap Index for males--methodological issues and data.

Reference data for speech range profiles (SRP), voice range profiles (VRP), and Voice Handicap Index (VHI) are presented for Swedish males (n = 30). For comparisons, individual data for four male contact granuloma patients are also reported. For the vocally healthy group mean values were: speaking fundamental frequency 123 Hz (SD 12.1), speaking equivalent level, Leq, 72.2 dB (SD 2.1), SRP area 142 STdB (SD 24.1), and VRP area 1,706 STdB (SD 340). Mean VHI was 5 (SD 4.8). Test-retest recordings of VRP and SRP for three subjects suggested good reliability. SRP and VRP values for three of the patients fell more than 2 SD outside the reference values. Protocols and results are discussed and standardized recording and analyses procedures are suggested.
