I record myself saying the word "titillate", followed by a very nice recording of the same word which I found from the internet and which I hope my voice can be trained to be as closer to as possible. The recording is here. Following is the waveform (on the top) and spectrogram (on the bottom) of the recording shown by Audacity (for a larger version, click here):
My recording is the first half, and someone else's is the second half. Some impressions I have are
- In our waveforms, mine looks sparser than the other's.
- in our spectrograms, the white areas are distributed differently.
What do those indicate? What are your impressions?
