Here, I am talking about the assimilated /t/ sound that is one of the most common features of Standard Southern British English (such as /t/ at the beginning of a syllable, time, task, Twitter, twice, etc.) as they are enunciated as /tts/ (neither full /ts/ nor /t/). If you pronounce /t/ sound as /t/ sound, there will not be any sound change taking place and I am afraid that you will not help me with this.
However, when these /tts/ sounds are preceded by affricatives or fricatives in a connected speech, I have noticed a possible sound change that the tongue will NOT necessarily get to the position that /tts/ is usually pronounced (right above the front teeth and below the alveolar ridge) but rather the tongue would simple be like hanging in the middle of the space without touching any place that it is supposed to touch when pronouncing /tts/ sound. There are also two exceptions towards this possible rule, first when /tts/ sound is stressed or second when there is a gap between these two sounds (as you read word by word)
I will give several examples for you as follows;
- It is time to go to bed! (/ts/+/tts/)
- He is my English teacher. (/ʃ/+/tts/)
- She is my Chinese teacher. (/z/+/tts/)
- i will see you next time (/s/+/tts/)
My question is is it a common sound change in English (especially in Southern British English) and the native speakers may not necessarily be conscious of this. Thanks, guys!
