Parametrize ai_operator_default_config() via AI_OPERATOR_* env vars,
falling back to the existing hardcoded defaults so the other two stacks
(call-center, sales-call-center) that share this code are unaffected.
Set aimaq-only overrides matching the client-provided script (Скрипт
ии-оператора КГА.docx): agent renamed to Жанна, company to Казакгаз
Аймак, the voice greeting now asks the caller whether Russian or
Kazakh is more convenient before anything else, and the base system
prompt instructs the model to commit to whichever language the caller
picks for the rest of the call, ask how to address them, and confirm
there's nothing else before saying goodbye.
RuntimeConfiguredTTSProvider (the live 'dynamic' TTS provider, resolves
voice from DB-backed config) never overrode cache_fingerprint(), so it
fell back to the base class's empty string. PrebakedAckBank keys its
on-disk cache on that fingerprint, so short filler phrases like
'Секунду' kept serving audio baked with the previous ElevenLabs voice
even after a voice change, while full LLM replies (cached inside the
resolved provider itself, keyed on its own voice id) already used the
new voice — explaining why callers heard two different voices in the
same call. Fix: delegate cache_fingerprint() to the resolved provider.
Also extend the voice delivery_hint so the model transliterates website
addresses and English words/abbreviations into spoken Cyrillic instead
of leaving raw Latin text for the TTS engine to mangle (egov.kz was
coming out as 'эговкз').
TTS reads raw text digit-by-digit with no number/date normalization layer.
Short numbers like 1414 were read as a single 4-digit number (tysyacha
chetyresta chetyrnadtsat) instead of a spoken code, and dates like '25
chisla' were read in the wrong grammatical case (dvadtsat pyat chislo
instead of dvadtsat pyatogo chisla). Extend the voice delivery_hint with
explicit spell-out rules so the model itself produces already-correct
spoken-form text.
