Why Voice AI May Be Better Than Text Chatbots

While text chatbots dominate this comparison, consider the limitations:

Text chatbot frustrations:

• Customers type slowly (40 WPM vs 150 WPM speaking)
• Complex issues don’t fit in chat bubbles
• Chat feels impersonal for high-value interactions
• Older demographics avoid chat entirely

Voice AI advantages:

• Faster communication (3x faster than typing)
• Handles complex conversations naturally
• Builds rapport and trust
• Works for all demographics
• Higher conversion rates

RealVoice AI bridges this gap by offering natural voice AI conversations alongside text chat—capturing opportunities other chatbots miss.

Conclusion

The “best” AI chatbot depends entirely on your specific needs:

• For B2B lead generation: Drift or Intercom
• For customer support: Intercom or Zendesk
• For small business: Tidio or Freshworks
• For voice + chat: RealVoice AI
• For budget-conscious: HubSpot Free or Tidio

Whatever you choose, ensure it actually solves problems for customers rather than creating new frustrations. The best AI chatbot is one your customers actually want to use.
