I see, so you're saying the vocal cords should always be vibrating during speech, like you're always maintaining a hum. This could work for some sounds but not for others. In the english language, there are sounds where are voiced ( with vocal cord activation) or unvoiced (no vocal cords involved, only air). For example you have paired sounds like D and T, B and P, S and ZH, all of which are share the same mouth positioning but one is voiced and the other is unvoiced. For example, D is the voiced version of the T sounds. There's also what's called stop consonants, where you have to forcibly, temporarily block air flow to make the sounds. Like B and P. For these sounds, a constant vibration of vocal cords would not be possible since you have moments where you have to cut off the air to make the desired sound. Also I agree with you about easy onset. I've had similar experiences using it. And easy onset would only work for vowel sounds and diphthongs. You would have to use the light touch/contacts technique for consonant sounds.
