Validate activity before betting a new project on dc_tts. ## When NOT to use speechbrain - If simplicity and ease of use are top priorities. SpeechBrain's extensive features might introduce unnecessary complexity for simpler speech processing tasks. - Avoid if you are constrained by computational resources, as expanding efforts toward training massive models could be resource-intensive and is one of the toolkit’s future development goals. ## Common questions ### What is the difference between dc_tts and speechbrain? dc_tts: A TensorFlow Implementation of DC-TTS. speechbrain: A PyTorch-based Speech Toolkit.
