Nothing gives away an AI receptionist faster than mispronouncing a town name or trade term, or dropping a live caller into dead air when a blind transfer goes unanswered.
Load phonetic pronunciations for local cities and trade terms, brief the receiving rep with a 5-second whisper summary during transfer, and pull the caller back if the rep doesn't answer within 15 seconds.
Configure custom pronunciation rules and safe warm transfers for our GoHighLevel Voice AI receptionist:
1. Build a phonetic pronunciation dictionary for our local service cities, owner names, and industry acronyms so the voice engine pronounces them naturally.
2. Replace blind call transfers with a 15-second Whisper Warm Transfer ("Press 1 to take this call from {{contact.first_name}}").
3. Add a fallback rule so if no human answers within 15 seconds, the receptionist apologizes warmly and texts the caller a direct booking link.

"timeout_seconds": 15,
"phonetic_terms": ["HVAC", "PEX", "SEER"],

# 2. Or run via ghl-agency Rust CLI

Keep every spoken response under 25 words, strip all markdown bullets from the voice prompt, and pair a 4-second DTMF greeting with a low-latency SIP bridge when sub-second response times are needed.
PLAYBOOK T01 · Voice AI & PhoneIncrease the Voice Activity Detection (VAD) pause threshold to ~400ms, keep spoken bot turns under 20–25 words, and ask only one question per turn.
PLAYBOOK T11 · Voice AI & PhoneConfigure pre-programmed DTMF dial strings with pause commas (e.g. `,1,2`) on known transfer numbers so the transfer bridges directly to the target extension instead of talking to an automated IVR.
PLAYBOOK T09 · Voice AI & PhoneKeep the business's main number on Google Business Profile so the front desk rings first for 15 seconds, then use Conditional Call Forwarding (*71) to roll unanswered and after-hours calls to your GoHighLevel Voice AI number.
