Dear list,
My research concerns the role of prosodic cues in speech perception in noise by older listeners. I have two methodological questions that I hope I can get some input from this great research community.
1. For my next project, I would like to use recorded sentences that are longer (>5 keywords) and syntactically more complex than IEEE sentences. Balanced lists, recording blocked by talker, and large number of sentences (>150) are preferred. I appreciate if anyone can direct me to any resource/information that is available.
2. My experiment also involves the design of degrading speech intelligibility while keeping changes on speech acoustic characteristics minimum (particularly voicing cues). I am considering vocoding and time-reversed speech for this purpose but also wondering what are other options that may preserve spectral/temporal features better.
Many thanks in advance!
Best,
Jing
