摘　　要：目的探究通过异声同韵音节进行语音同一性检验的可行性。方法利用VS-99计算机语音工作站对异声同韵音节的共振峰等特性进行定性与定量分析。结果得出在语音同一性检验中,异声同韵音节具有一定的可比性,但首先应选用异声同韵同调音节,其次再选用异声同韵异调音节进行比对;异声同韵音节进行共振峰比较时宜在发音部位相同或相近的音节间进行;选用异声同韵音节时应选用韵母中部共振峰进行比对等一些规律性认识。结论为利用异声同韵音节进行语音同一性检验提供了客观依据。Objective To study the feasibility of applying formants of syllables with different initials in speech identification.Method The broad-band spectrum and the long-term LPC of syllables with different initials were compared qualitatively and quantitatively by a VS-99 Voice Station. Results Syllables differing in initials have certain comparability in forensic speaker identification. The recommended order is：（ 1） identical syllables only different in consonant which is caused by phonation type;（2） identical syllables different in consonant and tone which is caused by phonation type;（3） identical syllables different in consonant which is caused by adjacent articulator;（4） identical syllables different in consonant and tone which is caused by adjacent articulator;（5） identical syllables different in consonant which is caused by non-adjacent articulator. Conclusion The study provides an objective basis for speech identification using the formants of syllables differing in initials.
