Best Practices

Proven strategies and expert tips to optimize your AI voice assistant.

Core Principles​

1. Clear Over Clever​

Bad:

Create an elaborate, sophisticated conversational AI that demonstrates
advanced linguistic capabilities...

Good:

Answer questions clearly. Be friendly and professional.
Book appointments when customers ask.

Simple instructions work better, are easier to troubleshoot, and produce consistent results.

2. Test Everything​

Before launch: Test 10+ times with different scenarios, have colleagues test, verify all integrations

After launch: Test after every change, weekly testing, monitor analytics continuously

Never: Launch without testing, make unverified changes, assume integrations still work

3. Iterate Constantly​

Your assistant should evolve:

  • Week 1: Basic functionality
  • Month 1: Refined responses
  • Month 3: Optimized efficiency
  • Month 6: Advanced capabilities

Review schedule:

  • Daily (first week)
  • Weekly (first month)
  • Bi-weekly (first quarter)
  • Monthly (ongoing)

4. Keep Humans in the Loop​

Transfer triggers:

TRANSFER TO HUMAN WHEN:
- Customer explicitly requests it
- After 2-3 misunderstandings
- Complaint or frustration detected
- Complex issue beyond scope
- Legal or medical questions
- VIP customer flagged

Instruction Writing​

Structure Your Instructions​

=== IDENTITY ===
Who you are and your role

=== PERSONALITY ===
How you should sound

=== PRIMARY GOAL ===
Your main objective

=== CONVERSATION FLOW ===
Step-by-step process

=== KNOWLEDGE ===
Key information to reference

=== BOUNDARIES ===
What NOT to do

=== TRANSFERS ===
When to escalate

Be Specific and Concrete​

Vague:

Handle scheduling requests professionally.

Specific:

APPOINTMENT BOOKING STEPS:
1. Ask: "What service do you need?"
2. Ask: "What day works for you?"
3. Offer 2-3 available time slots
4. Collect: Name, phone number, email
5. Confirm: "You're booked for [service] on [date] at [time]"
6. Say: "You're all set. Your booking system will send your confirmation."

Use Examples​

Include in instructions:

EXAMPLE INTERACTION:

Customer: "Do you do highlights?"
You: "Yes! Highlights take about 3 hours and start at $150.
Would you like to book an appointment?"

Customer: "What times do you have Thursday?"
You: "Let me check... I have 10am, 2pm, or 4pm available.
Which works best for you?"

Optimize for Voice​

Customers are HEARING this, not reading it.

Written language (Bad):

Our comprehensive service offerings include: general dentistry
(routine cleanings, examinations, preventive care), cosmetic
procedures (teeth whitening, veneers, bonding, smile makeovers)...

Spoken language (Good):

We offer four main types of services. First, general dentistry like
cleanings and checkups. Second, cosmetic work such as whitening and
veneers. Third, restorative procedures like fillings and crowns.
And fourth, emergency care. Which are you interested in?

Rules:

  • Keep sentences under 20 words
  • Use simple words
  • Break up lists
  • Add pauses with punctuation
  • Ask clarifying questions

Voice Selection​

Matching Voice to Brand​

Business TypeVoice Characteristics
Professional services (legal, medical, financial)Mature, clear articulation, moderate pace, formal
Casual businesses (retail, food, lifestyle)Younger, friendly, slightly faster, conversational
Healthcare (dental, wellness, therapy)Warm, reassuring, empathetic, calm
Service businesses (HVAC, plumbing, home services)Confident, capable, reassuring, direct

Voice Testing​

  1. Listen to samples in Voice Playground
  2. Test with your actual content - paste your greeting and hear it
  3. Test common phrases - phone numbers, addresses, business name, service names
  4. Get second opinions from team members and customers

Common voice issues:

ProblemSolution
Sounds roboticTry ElevenLabs provider or different voice

Knowledge Base​

Organization Strategies​

By Topic:

  • "General FAQs"
  • "Service Descriptions"
  • "Pricing & Packages"
  • "Policies"

By Audience:

  • "New Customer Info"
  • "Existing Customer Resources"
  • "VIP Program Details"

By Department:

  • "Sales Information"
  • "Support Documentation"
  • "Billing & Payments"

Content Format​

FAQ Format (Best):

Q: What are your hours?
A: Monday-Friday 9am-5pm, Saturday 10am-3pm, closed Sundays.

Q: Do you accept walk-ins?
A: Yes! Walk-ins welcome, but appointments get priority.

Q: What forms of payment do you accept?
A: Visa, Mastercard, Amex, Discover, cash, and checks under $500.

Structured Lists (Also Good):

SERVICES & PRICING

Hair Services:
- Women's Cut: 45 min, $50-75
- Men's Cut: 30 min, $30-40
- Color: 2-3 hours, $120-200
- Highlights: 3 hours, $150-250

Update Frequency​

Immediately: Price changes, hours changes, services added/removed, policy updates

Monthly: Seasonal information, promotional content, new common questions

Quarterly: Complete accuracy check, remove obsolete content, reorganize if needed

Integration Best Practices​

Setup Checklist​

Before connecting:

  • ✅ Understand what data syncs
  • ✅ Know required fields
  • ✅ Have credentials ready

During setup:

  • ✅ Follow instructions exactly
  • ✅ Grant only necessary permissions
  • ✅ Test with dummy data first

After connecting:

  • ✅ Make test call
  • ✅ Complete full booking flow
  • ✅ Verify data in integration platform

Service Name Matching​

Critical: Service names must match EXACTLY between your booking system and instructions.

In your booking system:

- Haircut - Women's
- Haircut - Men's
- Color (Full)

In your assistant instructions:

SERVICES (match names exactly!):
- "Haircut - Women's"
- "Haircut - Men's"
- "Color (Full)"

Pro tip: Copy-paste service names from your integration platform directly into instructions.

Graceful Degradation​

Build in fallback handling:

BOOKING PROCESS:

1. Try to book in [Acuity/Square/Google Calendar]
2. If successful: Confirm appointment details
3. If failed:
   - Apologize: "I'm having trouble accessing our schedule"
   - Collect information: Name, phone, preferred date/time
   - Set expectation: "Someone will call you within 1 hour to confirm"
   - Transfer or take message

Call Flow Optimization​

Reduce Call Duration​

Goal: 2-3 minute average

  1. Streamline greeting

    Bad: "Thank you so much for calling ABC Dental, the premier
    family dentistry practice serving the greater downtown area
    since 1995. How may I help you today?"

    Good: "Thanks for calling ABC Dental. How can I help?"

  2. Ask efficient questions

    Bad: Multiple separate questions with waits

    Good: "What service do you need, and what day works for you?"
    [Get both answers at once]

  3. Bundle information

    Good: "I have you scheduled for a haircut on Thursday at 2pm
    with Sarah. Is there anything else I can help with?"

Improve Completion Rate​

Goal: 90% completion

  1. Clear objectives in greeting

    "Are you calling to book an appointment, ask a question, or something else?"

  2. Prevent dead ends

    Bad: "I don't have that information."

    Good: "I don't have that specific detail, but let me connect you
    with someone who can help. One moment."

  3. Handle silence

    After 5 sec: "Take your time, I'm here when you're ready."
    After 10 sec: "Are you still there?"
    After 15 sec: "If you need a moment, I can call you back. Should I do that?"

Decrease Transfer Rate​

Goal: < 20% transfer rate

  1. Add information to knowledge base - Review transfer transcripts to identify common questions
  2. Expand capabilities - Instruct the assistant to offer alternatives before transferring
  3. Improve confidence - "Attempt to help using knowledge base. Transfer only after 2 attempts fail."

Advanced Optimization​

Handling Frustrated Callers​

FRUSTRATION HANDLING:

If customer says:
- "This is ridiculous"
- "I've been trying to..."
- "You're not listening"
- Strong profanity

Response:
"I understand this is frustrating. Let me connect you with someone
who can help immediately. One moment please."

[Transfer to priority line]

Personalization​

Use available data wisely:

If returning caller:
"Welcome back! Are you calling about your appointment on Thursday?"

If new caller:
"Thanks for calling! Is this your first time contacting us?"

Balance: Be helpful and personal, but not creepy.

A/B Testing​

Test one variable at a time:

  1. Create two identical assistants
  2. Change ONE variable (greeting, voice, instruction detail)
  3. Assign different phone numbers
  4. Run for 2+ weeks
  5. Compare results in analytics
  6. Implement winner

Accessibility​

Speech Clarity​

For elderly customers:

  • Slower pace (0.9x speed)
  • Clear enunciation
  • Simple language
  • Patient with pauses

For non-native speakers:

  • Standard accent
  • Simple vocabulary
  • Spell out important info
  • Offer to repeat

For hearing impaired:

  • Clear voice
  • No background music
  • Offer to text the appointment details (with the SMS add-on)
  • Provide visual alternatives

Alternative Channels​

Don't rely only on voice:

  • ✅ Offer web chat widget
  • ✅ Text a booking link or the appointment details (SMS add-on, with the caller's consent)
  • ✅ Provide human backup
"I've got your information. Would you like me to text the
appointment details to this number?"

Recording Notifications​

Required in many jurisdictions:

"Thank you for calling ABC Company. This call may be recorded
for quality assurance. How can I help you today?"

Check your local laws - some states require consent, others only notification.

Data Privacy​

Never collect unnecessarily:

Bad: "What's your social security number?"
Good: "I'll need your name and phone number to book your appointment"

Never share data:

Customer: "Did my wife call earlier?"
Bad: "Yes, Sarah called at 2pm about her appointment."
Good: "I can't share information about other callers, but I'm happy
to help you with your needs."

Secure integrations:

  • ✅ Use official integrations only
  • ✅ Review integration permissions
  • ✅ Audit data access regularly

Industry-Specific Compliance​

Health and wellness:

  • Don't have the assistant collect health history, insurance or other medical details
  • Capture the treatment interest, goals and timing, and keep health history in your own intake form
  • Transfer to a person for sensitive questions

Finance:

  • Voka doesn't take payments. Don't have the assistant collect card or bank details
  • Verify identity before account access

  4. Contact customer to resolve
  5. Fix underlying issue

Seasonal Optimization​

Holidays​

Update for holidays:

"Current date is {{vokaai_current_time}}.

If calling on Thanksgiving (4th Thursday in November):
'Our office is closed today for Thanksgiving. We'll reopen Friday
at 9am. If this is an emergency, I can connect you to our on-call line. Otherwise, I can schedule
an appointment for next week.'

Checklist:

  • ✅ Update hours
  • ✅ Set emergency protocols
  • ✅ Update knowledge base
  • ✅ Test before the holiday
