How Bloomlink bypassed cloud costs and data latency with a custom built, self hosted neural synthesis platform.

The Challenge

Bloomlink needed to bridge the gap between high end AI vocal quality and the strict requirements of local infrastructure. Most commercial TTS engines (like Google or AWS) charge per character, leading to unpredictable monthly overhead. Furthermore, for a telecommunications heavy environment, sending sensitive customer data to external clouds for processing introduced latency and security risks.

The mission: Build a self hosted, high fidelity Mongolian TTS system that sounds indistinguishable from a human, integrates with existing CRMs, and carries zero ongoing API licensing fees.

Our Approach

We engineered a specialized middleware layer that bridges a world class neural voice engine with Bloomlink’s internal systems. By leveraging a high quality, open source neural engine, we delivered the "gold standard" of Mongolian speech,smooth, natural, and perfectly accented,without the per call tax of big tech providers.

01
Neural Engine Integration
We utilized a high fidelity neural voice engine capable of sophisticated prosody. This allows the system to handle the complex tonal shifts of the Mongolian language without sounding robotic.
02
Telephony Optimized Audio
Unlike standard AI voices that output high bitrate files for music, we built a custom conversion pipeline. The system automatically outputs Asterisk compatible audio (1 channel, 8000Hz, 16 bit PCM WAV), ensuring seamless playback for automated call centers and IVR systems.
03
Linguistic Pre processing
Mongolian text presents unique challenges with numbers and symbols. We developed a custom pre processor that translates symbols (e.g., "38%") into their full phonetic Mongolian equivalents before they hit the voice engine, ensuring 100% accuracy in data delivery.
04
Containerized Deployment
Packaged the entire stack into a Docker based architecture, allowing Bloomlink to deploy and scale the TTS service across their own private servers in minutes.

The Results

Bloomlink transitioned from a conceptual need to a fully functional, enterprise grade voice infrastructure:

  • $0 Recurring Costs: By moving away from per character API billing, the system pays for itself in months.
  • Instant Integration: The API was built to match Bloomlink’s existing specs, requiring zero changes to their CRM or internal tools.
  • Infinite Scalability: Hosted on premise, the system can handle massive spikes in volume without hitting "rate limits" imposed by cloud providers.
  • Flawless Phonetics: 100% accuracy on currency, dates, and percentages in the Mongolian language.
