TTS Direction Algorithm Engineer

2 days ago


Singapore X Star Technology Pte Ltd Full time

Design and implement algorithms that direct or steer TTS output : e.g., controlling prosody, style, voice persona, emotion, pacing, emphasis, accent, dialect, intonation. Collaborate with researchers and engineers to take breakthroughs in speech synthesis and apply them to production-scale TTS systems. Work on components such as text normalization, phonetic/linguistic feature extraction, alignment modeling (text acoustic), prosody modeling, vocoder architectures or waveform generation. Build evaluation frameworks and metrics for naturalness, intelligibility, expressiveness, latency, voice persona fidelity, bias/fairness across languages and dialects. Create data pipelines and tooling for voice collection/labeling, human preference judgments, A/B testing for voice direction outputs. Optimize system latency, throughput, memory/compute requirements, streaming support, real-time constraints for voice in conversation. Ensure safe, inclusive, responsible voice output: avoid inappropriate style shifts, voice likeness issues, unintended biases or mis-interpretations. Collaborate with Safety, Policy, Product teams. Integrate the directed-TTS algorithms into product platforms (ChatGPT voice, developer API, accessibility features) and work with product/infra teams to ensure scalability and reliability. Qualifications Required MS or PhD in Computer Science, Electrical Engineering, Speech/Audio Signal Processing, Machine Learning, or equivalent experience. Proven experience in designing and shipping production-grade TTS or speech‐generation systems: e.g., text‐to‐speech, voice conversion, expressive prosody modeling. (E.g., the Voice AI role at OpenAI requires "building and shipping production voice or speech ML systems (TTS, voice cloning, or generative audio)".)Deep understanding of the speech synthesis pipeline: text normalization, linguistic/phonetic features, acoustic modeling, vocoder/waveform generation, prosody modeling. (Again, from the voice role: "Deep understanding of speech synthesis pipelines: text normalization, linguistic/phonetic features, acoustics, vocoding, and prosody modeling.")Strong ML engineering skills: Python + PyTorch (or another major framework), experience with data pipelines, model training/evaluation/serving, measurement of MOS/intelligibility/latency. Experience with audio tooling, data augmentation for speech, and evaluation metrics for naturalness/latency/persona fidelity. Excellent collaboration & communication skills; ability to work cross‐functionally with research, product, design, infrastructure, safety/policy teams. Preferred Experience with multilingual or dialectal voice systems, low‐latency streaming TTS, expressive or adaptive voice personas. Prior publication or contribution in speech synthesis, voice ML research (e.g., at top conferences, patents). Experience with large‐scale deployment of voice systems, optimizing latency/throughput in production (e.g., real‐time voice API processing). Familiarity with voice likeness / speaker identity protection / consent/licensing in voice systems. Experience with prosody control, emotion modeling, or voice style
