I'm trying to make a voicebank but certain vowels make this really strange popping sound. Every other voicebank I have sounds completely normal, without the strange sound I'm experiencing. When loading it in Audacity, the waveform looks like this.

Any help? I'm extremely new to UTAU so any help is appreciated. Sorry if I'm dumb.
