Role brief

aimlroles summary, based on the employer's posting.

What you'll do

  • Train text-to-speech systems that create realistic, expressive voices for entertainment and education
  • Test model designs and training data to improve speech quality and generation speed, then deploy the strongest results
  • Track new speech research and identify changes worth testing in the models
  • Work with three TTS researchers, alongside engineering and hardware teams supporting deployment

What you bring

  • You have trained text-to-speech or voice-cloning models
  • You understand transformers, diffusion models, GANs, and how speech audio is processed
  • You are proficient in Python and libraries such as PyTorch or Hugging Face Transformers
  • You can interpret research papers, implement methods, and apply strong machine-learning fundamentals

Who this fits

This contractor role suits a mid-level researcher focused on text-to-speech, working closely with a small research team. The position is remote.

From the employer

About Valka.ai Valka, a visionary spin-off from the Realms Group (the parent company of Oddin.gg), is on a mission to revolutionize the way people create and experience digital content. Our team believes that content shouldn’t just be consumed; it should be co-created in real time, blurring the lines between imagination and reality. By harnessing the power of cutting-edge AI, we aim to build an interactive human-digital platform where virtual characters respond dynamically to each user’s voice, text, gestures, and more. This is your chance to join a diverse group of innovators who are driven to redefine what’s possible in generative content. Together, we’re changing the paradigm from passive viewing to active participation, unlocking new creative frontiers across gaming, entertainment, education, and beyond.

What you will be doing

  • Research and train fast and quality SOTA TTS models for realistic and emotional voice generation for entertainment and education applications.
  • You will be experimenting with different architectures / data to improve the quality and speed of the TTS model(s) and put the best results to production.
  • Staying up to date with current research and coming up with new ideas / what to improve is very important for us!
  • You will be in immediate collaboration with a team of 3 researchers specializing in TTS, and the product is supported by engineering and hardware stuff to ensure deployment

Skills you need

  • Experience with training some text-to-speech / voice cloning models
  • Solid knowledge of transformers, diffusion models, GANs
  • Understanding of human speech and audio processing (sampling, spectrograms, vocoders)
  • Proficiency in Python and key libraries (e.g., PyTorch, Hugging Face Transformers).
  • Ability to keep up to date with research, understand papers, implement approaches; strong ML fundamentals and critical thinking
    • Nice-to-have:
  • Familiarity with modern speech synthesis models (GPT-based, flow matching… such as Vevo, StyleTTS, IndexTTS, Maskgct etc.)
  • Contributions to open-source AI tools or research publications in Speech processing field
  • Familiarity with AWS / similar clusters
