Speech Recognition
Building automated speech-to-text (STT) engines and acoustic models for call center transcription and voice command systems.
Capability overview
What speech recognition involves
Speech Recognition converts spoken human audio into accurate digital text transcripts. We engineer high-performance Speech-to-Text (STT) models and transcription pipelines using Whisper, Kaldi, Wav2Vec2 and custom acoustic models.
We build speech recognition engines tailored to domain-specific terminology, heavy accents, noisy call environments and specialized medical or legal jargon.
Our speech-to-text solutions automate call center quality auditing, generate meeting transcripts and power voice-controlled software interfaces.
During the speech recognition engagement, our specialists work closely with your technical leads to establish tailored operational workflows, automated validation controls and clear deliverables for custom vocabulary stt fine-tuning and real-time streaming voice transcription. From initial audio data & noise profile audit through to model selection & fine-tuning, we embed continuous telemetry monitoring, structured documentation and risk mitigation rules tailored specifically for your organization's speech recognition goals and call center audio quality auditing requirements.

What is included
What the engagement covers
Custom Vocabulary STT Fine-Tuning
Fine-tuning speech-to-text models on proprietary product names, medical terms and industry jargon.
Real-Time Streaming Voice Transcription
Engineering low-latency audio streaming pipelines for live call transcription and voice command systems.
Call Center Audio Quality Auditing
Transcribing high volumes of recorded customer support calls for compliance auditing and analytics.
Multi-Speaker Diarization Pipelines
Separating multi-speaker audio recordings into distinct speaker turns (e.g., identifying Agent vs Customer).
How we work
How we deliver speech recognition
Audio Data & Noise Profile Audit
Auditing sample audio formats, bitrates, background noise levels, speaker accents and domain vocabulary.
Model Selection & Fine-Tuning
Fine-tuning OpenAI Whisper or Wav2Vec2 models on domain audio files using custom language model rescoring.
Speaker Diarization Integration
Integrating PyAnnote or DeepFilterNet to separate speaker turns and cancel ambient background noise.
Streaming API Microservice Setup
Deploying WebSocket and gRPC microservices for real-time streaming audio transcription.
Word Error Rate (WER) Evaluation
Benchmarking Word Error Rates (WER) on domain test sets and adjusting language model weights.
