It's rather /strentθ/. The /t/ is particularly difficult to hear, so I slowed it down by 30 per cent for the last two snippets.
Now which processes are needed in which order to make the change from /streŋkθ/ to /strentθ/ plausible?
1. Delete the /k/.
2. By regressive assimilation the /ŋ/ becomes /n/ due to /θ/.
3. An epenthetic /t/, which is dental, is inserted surrounded by dental /n/ and /θ/.
