Why Is My AI Voice Sounding Robotic? Improve Voice Quality
Fix robotic or unnatural AI voice quality in Local Business Pro. Adjust voice settings, stability, and similarity for natural conversations.
Quick Answer: Robotic-sounding AI voice is usually caused by voice stability settings being too high or speaker boost being disabled. Navigate to AI Logic > Receptionist > System Settings to adjust Voice Stability and Voice Similarity sliders for more natural speech.
What You'll Learn
This guide explains how to improve your AI receptionist's voice quality by adjusting system settings and selecting the right voice for your business.
Step-by-Step Solution
- Navigate to AI Logic > Receptionist
- Scroll down to the System Settings section
- Adjust the Voice Stability slider - lower values (30-50%) create more expressive, natural speech
- Adjust the Voice Similarity slider - higher values (70-90%) make the AI sound closer to the selected voice
- Enable Speaker Boost for increased similarity to the original voice
- Save your changes and test with a voice call
Common Causes
- Voice Stability too high: Settings above 70% can make speech sound monotonous and robotic
- Wrong voice selection: Some voices are naturally more expressive than others - try a different voice
- Speaker Boost disabled: Enable this for richer, more natural-sounding speech
- Personality traits missing: Add personality traits like 'Friendly' or 'Enthusiastic' to encourage natural variation
Understanding Voice Settings
Local Business Pro provides two key sliders for voice control:
Voice Stability (0-100%): Controls how consistent the voice sounds. Lower values = more expressive and varied. Higher values = more consistent but potentially robotic.
Voice Similarity (0-100%): Controls how closely the AI matches the selected voice sample. Higher values sound more like the original voice.
Recommended Settings by Use Case
| Use Case | Stability | Similarity | Speaker Boost |
|---|---|---|---|
| Friendly receptionist | 35-45% | 75-85% | On |
| Professional/formal | 55-65% | 80-90% | On |
| Casual/conversational | 25-35% | 70-80% | On |
Try a Different Voice
If adjusting settings doesn't help, try selecting a different AI voice:
- Click the AI Voice dropdown in the Receptionist section
- Select Select a new voice...
- Preview multiple voices by clicking the play button
- Choose a voice that sounds naturally expressive
- Save and test with a voice call
Frequently Asked Questions
Q: Why does my AI sound different in test calls vs real calls?
A: Phone call quality can affect how the voice sounds. The test feature uses higher quality audio. Adjust stability slightly lower to compensate for phone compression.
Q: Will changing voice settings affect what my AI says?
A: No, voice settings only affect how the AI sounds, not what it says. Conversation logic and scripts remain unchanged.
Q: How often can I change the voice?
A: You can change voice settings as often as needed. Changes take effect immediately on the next call.
