this is my first post here, wasnt too sure where to put it, forgive me if wrong choice …
Not sure anyone else finds this useful, it helped me have my automations respond via voice/notifications a bit more entertaining 
This jinja macro allows you to define multiple sentences and reference them with keys.
e.g. Respond with “yes”, “cool”, “alright” varyingly. Does support variable substitution (“Yes, %name%” → “Yes, Tamay”).
Keys & phrases get defined in /custom_templates/phrases/topic.jinja
The macro needs to be placed at /custom_templates/phraser.jinja
Code for phraser.jinja:
{# build a sentence #}
{%- macro phraseit(context, topic, key, replacementarray = []) -%}
{%- set ns = namespace(data=[], macro_output = 'empty') -%}
{%-for ptopic in context.glossary if ptopic.0 == topic -%}
{%- set ns.data = ptopic.1[key] -%}
{%-endfor-%}
{%- set ns.macro_output = ns.data | random -%}
{%- if replacementarray is defined and replacementarray is iterable and replacementarray|count > 0 -%}
{%- for rakey,ravalue in replacementarray.items() -%}
{%- set ns.macro_output = ns.macro_output | replace('%'+rakey+'%', ravalue) -%}
{%- endfor -%}
{%- endif -%}
{{ ns.macro_output }}
{%- endmacro -%}
{# combine glossary files #}
{%- macro loadglossary(topic) -%}
{%- set gfile = 'phrases/'+topic+'.jinja' -%}
{%- import gfile|string as glossary -%}
{%-if glossary is defined and glossary.phrases is defined -%}
{{ glossary.phrases|tojson }}
{%-endif-%}
{%- endmacro -%}
{# load initital context #}
{%- macro init_context(phraseids) -%}
{%- if phraseids is defined and (phraseids is string or phraseids is iterable) -%}
{%- if phraseids is string and phraseids|length > 0 -%}
{%- set phraseids = [phraseids] -%}
{%- endif -%}
{%- if phraseids is iterable and phraseids|count > 0 -%}
{%- set nsg = namespace(gdata=[]) -%}
{%-for pid in phraseids -%}
{%-if pid is defined -%}
{%- set nsg.gdata = nsg.gdata + [(pid,(loadglossary(pid)|from_json))] -%}
{%-endif-%}
{%-endfor-%}
{%- set pcontext = {
'topics': phraseids,
'glossary': nsg.gdata
}
-%}
{{ pcontext|tojson }}
{%- endif -%}
{%- endif -%}
{%- endmacro -%}

]
}
-%}
Initiate context supports either one topic specified as string or multiple topics specified as array of strings. Topics are key files that get placed in /custom_templates/phrases/
To be used in templates as following:
{% import 'phraser.jinja' as px %}
{% set phrases = px.init_context(['generic','windwarning']) | from_json %}
{{ px.phraseit(phrases, 'windwarning', 'ask_to_close', {'name':'Tamay'}) }}
