Notch

When expanding into voice automation, Notch faced a demanding set of requirements. Their enterprise clients rely on customer conversations that are immediate, precise, and trustworthy where tone, clarity, and timing directly affect the customer experience.

Unlike scripted or short responses, Notch’s agents manage extended, context-rich calls such as insurance claims, travel itinerary changes, e-commerce returns, and account verification. Each call demands a conversational flow that feels authentic and emotionally aware, regardless of language or duration.

To succeed, Notch needed a voice solution that could deliver human-quality audio in real time, respond instantly without latency, and scale across dozens of languages. It also had to capture cultural and linguistic nuance, accurate pronunciation of names, addresses, and technical terms while maintaining emotional tone and consistency throughout multi-minute conversations.

Conventional voice technologies could not meet these simultaneous demands for performance, naturalness, and global scalability. Notch turned to Deepdub to achieve all three

Deepdub integrated its proprietary eTTS™ (emotive Text-to-Speech) technology into Notch’s voice platform to enable natural, expressive conversations at enterprise scale.

By combining Deepdub’s advanced speech generation models with a dedicated pronunciation and linguistic pipeline, Notch was able to achieve high-quality, low-latency interactions in Hebrew and begin expanding to more than 70 languages. Deepdub’s API-based architecture ensured seamless integration into Notch’s existing conversational AI stack, allowing the company to move from development to production rapidly.

The result was a system capable of responding in approximately 180 milliseconds, sustaining natural dialogue across long exchanges, and adapting to the emotional context of each conversation. Whether explaining an insurance policy, confirming a booking, or guiding a customer through troubleshooting steps, the Deepdub-powered voice maintained a calm, clear, and human tone-essential for building trust and delivering a satisfying support experience.

By integrating Deepdub’s eTTS™ voice technology into Notch’s AI pipeline, enterprise clients were able to extend their existing chatbot and support systems into fully conversational, real-time voice experiences without additional human resources or infrastructure overhead.

This integration delivered substantial operational gains. Notch’s clients reported a 70% reduction in manpower requirements and a 50% overall cost saving, achieving rapid ROI after deployment. Deepdub’s ultra-low-latency voice generation consistently below 200ms and now approaching 100ms ensured each conversation began instantly and flowed naturally from start to finish.

With Deepdub’s ability to generate speech at over 4X real-time speed, once the first second of voice was streamed, the entire conversation was secured and pre-rendered guaranteeing stable, high-quality performance even in extended or complex dialogues.

These combined capabilities allowed Notch’s enterprise clients to scale customer service operations efficiently, maintaining the warmth and reliability of human interaction while realizing measurable savings in time, cost, and labor.
