You will get PRISM: framework to capture 50% more errors at fraction of the RLHF budget
Project details
What sets this project apart is the shift from "brute-force" manual review to targeted, data-driven refinement.
Most organizations scale TTS quality by throwing more human hours at the problem—a method that is slow, expensive, and prone to inconsistency. My approach, via the PRISM (Phonetic Refinement & Intelligent Speech Modelling) framework, uses high-precision IPA distance metrics to "Deepseek" model failures.
By mathematically identifying exactly where prosody and pronunciation drift from the target, I eliminate 80% of the manual "noise." This allows your native-speaker experts to focus only on the most critical errors. The result is a premium, human-grade voice output delivered at a fraction of the traditional time and budget, providing a clear path to ROI for high-scale AI deployments.

Whether you need to architect a world-class service model or refine high-stakes AI training data, I provide a results-oriented approach that balances deep operational expertise with modern, AI-inspired precision.
Core Frameworks & AI-Inspired Services
1. PRISM: Phonetic Refinement & Intelligent Speech Modelling
I utilise the PRISM framework to reimagine the TTS (Text-to-Speech) enhancement lifecycle. By blending large-scale automation with selective human validation, I help clients compress development timelines while drastically improving pronunciation accuracy.
- Phonetic Precision: Identifying true phonetic errors through IPA (International Phonetic Alphabet) distance analysis.
- Scalable Benchmarking: Automating large-scale evaluations against "Golden Reference" models (e.g., Google, Azure, ElevenLabs) to ensure the strongest baseline.
- Selective RLHF: Learning from selective Reinforcement Learning from Human Feedback to refine speech models.
- Efficiency: Delivering up to an 87% reduction in cost per error with high error detection recall.
2. STRATA: Secure Transcription & Review Architecture
As a "Data Custodian," I deploy the STRATA framework to handle high-volume, high-sensitivity datasets for IoT (smart home), Legal, and Medical sectors. This three-layer path ensures "Ground Truth" accuracy without risking privacy.
- Layer 1 (Tactical AI Triage): 100% automated multi-engine ASR/STT for 3x delivery speed and initial PII tagging.
- Layer 2 (Hybrid Synthesis): AI-inspired ambient event logging (e.g., laughing, TV noise) refined by Human-in-the-Loop (HITL) agents.
- Layer 3 (The Adjudicator Protocol): 100% human, deep-context audit to eliminate AI hallucinations and ensure 99% accuracy.
- Compliance: Full PII redaction and de-identification for defensible, legal-grade records.
CX Strategy & Process Excellence
Beyond AI data, I continue to drive value through traditional CX and PE consulting:
- Contact Centre Optimisation: Full setup, outsourcing strategies, and workforce planning for high-performing service environments.
- Metric Enhancement: Targeted interventions to improve NPS, CSAT, and CES.
- Automation Design: Deploying IVR, chatbots, and multi-channel integrations (WhatsApp/Chat) to reduce costs and improve productivity.
- Process Excellence: Lean Six Sigma-driven audits and resource optimisation for dynamic, global workloads.
Why Work With Me
- Dual Expertise: 20+ years of operational leadership combined with specialised expertise in the AI-Speech modelling lifecycle.
- Global Reach: Native-level expertise in English, Germanic, Latin-derived, Indic, and Arabic linguistic coverage.
- Certified Precision: Lean Six Sigma, Google Cloud, and Project Management Professional.
Let’s collaborate to transform "messy" real-world audio into structured, compliant intelligence, elevating your business operations through innovative, AI-driven solutions.
Steps for completing your project
After purchasing the project, send requirements so Shubh can start the project.
Delivery time starts when Shubh receives requirements from you.
Shubh works on your project following the steps below.
Revisions may occur after the delivery date.
Step 1: Automated Phonetic Auditing
I run your current TTS outputs through the PRISM framework to mathematically compare them against reference models. Using IPA distance metrics, I pinpoint exactly where your model is drifting in pronunciation or prosody.
Step 2: Targeted Human-in-the-Loop Refinement
Instead of a general review, I lead a precision-focused labeling sprint with native speakers. We focus exclusively on the "high-error clusters" identified in Step 1, maximizing recall while minimizing labeling costs.
