Detecting words starting with the same letter

Hi, is there a way to detect consecutive or nearby words starting with the same letter? For example, “detecção de defeitos desativada”, or “seguir os seguintes passos”.

Thanks in advance!

The following search may help you:

Source or Target term: "<([a-z])=1[^[:space:]]+>( <[^[:space:]]+>)?(@1[^[:space:]]+)+"
Search mode: Regular Expressions
PowerSearch: On
