About Blue Machines and the Speech Research team
Blue Machines (ApnaTime Tech Pvt. Ltd.) builds enterprise voice AI agents for banks, insurers, healthcare and telecom companies. Our platform has handled tens of millions of production voice minutes, is ISO 27001/27701 and SOC 2 Type II certified, and runs both on cloud and on-prem.
We already run our own models in production: Aurora (STT tuned for BFSI), Floe (language-switch detection), end-of-utterance models, and noise cancellation, all on BM Zap, our low-latency voice framework. The Speech Research team takes this further: better accuracy on Indian languages and code-mixed speech, natural expressive TTS, and full-duplex speech-to-speech models that cut latency across the whole conversation.
What makes this work different
• Real traffic: your model ships to live enterprise calls, not a leaderboard
• Hard problems: 8 kHz telephony audio, Hinglish and code-switching, accents, noisy environments, domain entities (loan numbers, policy IDs, names)
• Tight latency budgets: streaming inference where every 50 ms is noticed by callers




• A full loop: data, training, evaluation, serving and production feedback in one team

Senior ML Research Scientist, Speech (3–6 years)
You will own a research direction (STT, TTS or speech-to-speech) end to end. That means designing recent architectures, pre-training foundation models from scratch on large multilingual audio, and getting them into production, while mentoring engineers on the team.
What you will do• Lead one research track and set its roadmap with the CTO and product leads, tied to customer metrics (accuracy, naturalness, latency, cost per minute)
• Design novel architectures and pre-train speech foundation models from scratch on large multilingual corpora (100k+ hours), including self-supervised pre-training, tokenizer and codec design, and scaling experiments. Fine-tuning and continued
