What is Voicebot
Voicebot combines voice recognition + AI to answer:
Customer calls → voicebot listens to questions → answers by voice.
Can handle: asking for time, checking applications, confirming information, giving instructions.
When the customer needs someone or has difficulty asking questions → transfer to the operator.
Quick distinction:
Type | Interaction | Example
IVR | Key press | "Press 1 for customer service"
Chatbot | Gõ chữ | Chat website, Messenger
Voicebot | Talk | Call, answer by voice
Lợi ích của voicebot
1. On call switchboard 24/7
Customers who call late at night will still be answered, they don't have to wait until morning.
It's not "out of hours no one answers the phone".
2. Reduce agent load
Repeated questions are handled by the voicebot, the operator focuses on difficult tasks.
Reduce operating costs (see AI containment).
3. Quick reply
No waiting in line, voicebot responds instantly.
Customers do not have to "hold on hold".
4. Consistent quality
Answer according to the standard script, not "the operator is happy/tired today".
Limitations of voicebot
1. Vietnamese accent is not perfect
Identify regional accents and slang words with errors.
Guest speaks quickly, with a low voice → voicebot mishears (see Vietnamese Voicebot).
2. Customers are afraid to talk to the machine
Many customers find the "machine" annoying and want to meet someone immediately.
If a customer requests to meet someone but does not transfer → the customer is lost.
3. Unable to handle complex situations
Complaints, sensitive situations, and high emotions all need someone to handle.
Voicebot doing something wrong in a difficult task is more harmful than not doing anything at all.
When to use voicebot
Recommended:
Large volume of repeated questions (working hours, address, application form).
Time difference: customer calls out of hours.
First stage of reception: ask for needs, classify before transferring to the operator.
Not recommended for:
Complicated complaints, angry customers.
High-value sales consulting needs convincing.
Golden rule: Always have a quick way to transfer people, customers "tell people" as soon as they request.
