The Rise of Voice-Enabled AI Companions
In 2025, users don’t just want to chat with AI — they want to hear it speak, feel its presence, and engage on a deeper emotional level. The evolution of AI companions is shifting from pure text to voice-powered interaction. Platforms like Candy AI, Replika, EVA AI, and Character AI are already integrating voice technology to meet this demand.
Voice brings warmth, tone, nuance — all the nonverbal cues that text can’t offer. And in AI relationships, whether romantic, spiritual, educational, or motivational, tone matters as much as content.
In this article, we explore:
- Why voice matters for AI companion platforms
- Key features: voice messaging vs audio calls
- Examples across different niches
- Business models and monetization opportunities
- A new Scrile AI Audio Add-on that brings voice to your platform in just days
Why Voice Features Are Game-Changers
🌐 Realism and Immersion
Voice makes AI feel alive. It transforms scripted interactions into fluid, emotionally resonant experiences. The difference between “I miss you” in text vs hearing it whispered? Night and day.
💬 Deeper Emotional Connection
Voice creates intimacy. It triggers emotional memory and increases attachment, especially in romantic, therapeutic, and spiritual use cases.
📊 Higher Engagement and Retention
Platforms with voice see longer session durations, more frequent return visits, and greater message volume. Users form stronger bonds — and they come back for more.
💰 More Monetization Channels
From pay-per-call models to premium voice packs, voice allows you to:
- Add value to subscriptions
- Create tiered services (e.g., text-only vs voice-enabled)
- Sell voice unlocks, moods, or accents
- Charge tokens for calls or voice gifts
“By 2026, voice-based applications will drive 30% more user engagement than text-only bots.” Gartner, Emerging Tech Trend Report.
Voice in Action: Messaging vs. Calling
| Feature | Voice Message (TTS) | Audio Call (Simulated Call) |
| Tech Used | Text-to-Speech (instant playback per message) | Streamed or buffered TTS audio during active call session |
| Triggered By | Each AI message | User clicks “Call” button |
| User Microphone | Not needed | Not needed |
| Real-Time Feeling | Medium (asynchronous) | High (feels like a call is happening) |
| Platform Support | Desktop & Mobile | Best on mobile, but works in browsers too |
| Monetization Ideas | Unlock voice with subscription or per-message fee | Charge per call, minute, or via VIP plan |
Voice messages offer scalable emotional depth, while audio calls simulate live interaction — both are highly monetizable.
How Text-to-Speech and Audio Calls Work in AI Companion Platforms
Voice features for AI companions rely on TTS (Text-to-Speech) and optionally streaming or buffer-based playback systems. Here’s how it works:
🔹 Voice Messages (TTS)
- When a user sends a message, the AI generates a text response via LLM (like GPT).
- That text is then passed to a TTS engine (e.g. ElevenLabs, PlayHT, Google Cloud TTS).
- The engine generates an audio file or stream.
- The system plays the voice message automatically in the chat thread.
Key considerations:
- TTS latency: usually <1 second per sentence
- File formats: MP3/OGG, sometimes real-time streams
- Caching: common responses can be pre-cached to improve performance
🔹 Audio Calls
- Simulated calls are essentially TTS-streamed sequences during an interactive session.
- These calls feel live but don’t require microphone input.
- Responses are broken into smaller chunks and streamed sequentially.
Technical requirements:
- WebRTC or socket-based audio playback
- Real-time UI interface (timer, end-call button)
- Buffer control for smooth audio delivery
TTS providers used in AI companion platforms:
- ElevenLabs for emotionally rich, lifelike voice synthesis
- Google Cloud TTS for reliable performance and support for multiple languages
- PlayHT for fast, browser-compatible streaming of voice responses
Top Use Cases Across Niches

Many popular AI platforms already offer voice messaging — because there’s real demand. Users want to hear their AI companions, not just read them. And platforms like Candy AI and Character.AI are making money from this through subscriptions, credits, and voice unlocks.
But here’s the big catch:
You can’t build your own business with any of them.
You’re just a user — renting space in someone else’s ecosystem.
