Yampa is scaling high-intensity outbound voice intelligence with ElevenLabs

Yampa, a leader in conversational AI based in France, is redefining the limits of automated outbound communications. By integrating ElevenLabs Flash V2.5 into their proprietary orchestration layer, Yampa has successfully deployed high-scale voice agents capable of managing hundreds of simultaneous interactions with human-like precision.

The Challenge: The “Same-Second” Scalability Hurdle

For Yampa, the primary operational challenge lies in executing high-intensity outbound call campaigns where timing is everything. Traditional text-to-speech (TTS) solutions often struggle with:

• Massive Concurrency: Initiating hundreds of calls at the exact same second without performance degradation.
• Latency Spikes: Maintaining low response times during high-volume bursts, which is critical for conversational flow.
• Operational Stability: Ensuring that voice quality remains consistent even when the system is under extreme load.
  

The Solution: High-Performance Orchestration

To solve these bottlenecks, Yampa developed a proprietary TTS-LLM-STT orchestrator. This system manages the complex requirements of streaming, timing, and concurrency across the entire voice pipeline.

Yampa chose ElevenLabs Flash V2.5 as the backbone of this infrastructure. This partnership allowed Yampa to:

• Enable Instant Interaction: AI agents can speak instantly, mirroring the reactivity of a human representative.
• Maintain Voice Quality: Even under heavy outbound loads, the agents deliver the natural, lifelike audio ElevenLabs is known for.
• Scale Without Limits: The integration provides the stability needed to trigger more than 500 simultaneous calls without hitting a performance ceiling.
  
  

The Results: Measurable Impact on Outbound Performance

After six months of production usage, the combination of Yampa’s orchestrator and ElevenLabs Flash V2.5 delivered transformative results for their clients:

"Flash V2.5 integrated into our orchestration layer gives us the reactivity and stability needed to run outbound calls at massive scale, without sacrificing quality." — Marin Huet, Yampa

Future Outlook: Real-Time Intelligence

Following the success of their TTS implementation, Yampa is exploring the use of ElevenLabs' Real-time STT (Speech-to-Text) in the French market. This next phase focuses on further reducing end-to-end latency and enhancing the responsiveness of their autonomous agents to create even more seamless and effective customer engagements.
