Train a custom wake word
The training center walks you through four simple steps: pick a wake word, estimate cost, choose between a single training run or an Optuna hyperparameter search, and launch the job on our GPU workers. You can watch progress live and download the finished model straight from the training page.
Synthetic training data
Positive samples are generated with Piper TTS across many voices and languages, then augmented with real-world noise and room impulse responses. Adversarial negatives are generated from phonetically similar phrases to reduce false activations.
Single run or Optuna search
A single run is the fastest way to get a usable model. Optuna mode runs multiple trials over training steps, negative class weight, and learning rate, then keeps the best performers and publishes them with an Optuna badge in the library.
Credits and pricing
Training is billed in credits based on sample count and Optuna trial count. You can buy credits from your account page. Failed jobs are refunded automatically.
