Text-to-Speech for IVR greetings

Create professional voice greetings without recording audio — just type the text.

How TTS works

AIsoule uses Piper TTS (an open-source neural TTS engine) to convert your text into natural-sounding speech.

Creating a TTS greeting

1. In the IVR flow editor, add a Play Message node
2. Select input type: Text-to-Speech
3. Type your greeting:

   Welcome to AIsoule. For sales, press 1. For support, press 2. To speak with an agent, press 0.
   

4. Select voice (language/accent)
5. Click Preview to hear it
6. Save

Available voices

• English (US) — Male/Female
• English (UK) — Male/Female
• Hindi — Male/Female
• Additional languages available

Tips for good TTS

1. Use punctuation — Commas add natural pauses
2. Keep sentences short — Easier to understand over phone
3. Spell out numbers — "Press one" sounds better than "Press 1"
4. Test and iterate — Listen to the output and adjust wording
5. Consider recording — For brand-critical greetings, professional recording sounds better
