(Text-to-speech) Break, Rate, Pitch is a problem with the Thai voice.

Question

They'll stop 1 second after reading the first word, even if I state that 100ms, or even pitch and rate, are also problematic. They will always stop for 1 second between words.

I have already used these commands and encountered problems.

1. ฉัน<break time="100ms" />รัก<break time="100ms" />เธอ
2. ฉัน<prosody pitch="+10.00%">รัก</prosody>เธอ
3. <prosody rate="-10.00%">ฉัน</prosody>รักเธอ

While using the Thai voice (th-TH-PremwadeeNeural), I tried changing the word to English.

1. I<break time="100ms" />love<break time="100ms" />you
2. I<prosody pitch="+10.00%">love</prosody>you
3. <prosody rate="-10.00%">I</prosody>love you

But the problem still remains.
It doesn't work well with Thai. While other languages don't have this problem, even "Lao" languages with a structure similar to Thai work smoothly.

I'm waiting for the day this problem will be resolved.
Best regards,
