customized template error

[elf7979]

I want to extract one person's speech so I used this:

{% for st in subtitles %} {% if st.speakers != 'speaker name' %} {{ st.text }} {% endif %} {% endfor %}

I believe this code will help me get all speechs excluding "speaker name's speech" but it worked the other way around. Speaker name's speech only were left using this code. Obiviously, I finished tagging on segmented speech.

I was wondering if you could help me for this. Thanks
