Set the energy. Match your room.

Tone is independent of voice. Pair Rachel with a Professional tone for a polished clinic vibe, or with a Friendly tone for a warm salon greeting. Three tones cover most use cases. Switch anytime.

The problem

Same words, different energy.

A friendly greeting at a med spa lands differently than a friendly greeting at a personal injury law firm. Tone is the difference between 'we get you' and 'we're trying too hard.'

Della's tone setting modifies the AI's prosody, pacing, warmth, formality, without changing the voice itself. Friendly is conversational and energetic. Professional is polished and direct. Calm is slow and reassuring. Pick the one that matches the emotional state your callers arrive in.

FAQ

Common questions.

Still unsure? Call Della at +1 (818) 918-4562 and ask her.

Can I create a custom tone?

Pro tier supports custom tone definitions via prompt instructions. Useful for specific brand voices ('warm but not casual,' 'authoritative but not cold').

Does tone affect the words Della says?

Not the content (those come from your scripts), but the delivery, pacing, emphasis, warmth. Same script, different energy.

How do I A/B test tones?

Switch tones for a week and compare booking conversion in your analytics. Many salons see 5-10% lift moving from Friendly to Professional, depending on demographic.
