Manipulation of Phonemes in Natural Speech

Nonsense Syllables

  • ka 2 ta 2 pa m4v, wmv; Three different conditions (1-3) are played, with the AI gram showing for each. You might either hear /ka, ta, pa/ or /ka, pa, pa/. Listen for one, and then the other. Here is what we have done:
    1. You should always hear /ka/, as this is unmodified speech.
    2. You may hear /ta/ or /pa/. Here we have removed the mid-frequency /ka/ burst. See what you naturally hear first. Then try to listen for the other of /ta/, /pa/. This depends on your first language, and should only work for L1=English listeners.
    3. You should always hear /pa/. Here both the /ka/ and /ta/ acoustic cues have been removed.

* ka 2 ka 2 ta 2 pa wmv Δ

  • ba 2 ga m4v, wmv @ 12 [dB-SNR]; Here there are two presentations:
    1. The natural /ba/ in 12 dB SNR of Noise. With no masking noise, it is 85% /ba/, else /va/. At 10 dB SNR it is /va/ 50% of the time. At 12 dB SNR it is frequently heard as /va/.
    2. The mid-frequency (i.e., /ga/) burst enhanced & the low-frequency onset removed. Many report it as /ga/.
