Job Description
Representative responsibilities/duties will include but not limited to:
• Design and optimize text/NLP preprocessing pipelines with Deep Learning or Machine Learning methods, including Grapheme-to-phoneme (G2P) conversion for multilingual support; Text normalization; polyphone disambiguation; Prosody prediction and control
• Integrate language models (e.g., BERT, GPT variants) to improve contextual and semantic understanding for natural intonation
• Develop rule-based and neural solutions for emotion/style control in synthesized speech
• Build state-of-the-art acoustic models (e.g., Tacotron, FastSpeech, VITS) to map linguistic features to spectrograms or waveform parameters.
• Optimize neural vocoders (e.g., WaveNet, HiFi-GAN, MelGAN, LPCNet) for high-fidelity, real-time speech synthesis
• Optimize inference latencies for both edge devices and cloud platforms
• Enhance robustness through noise suppression, speaker adaptation, and multilingual/cross-language/cross -gender voice cloning
