NVIDIA NeMo is a conversational AI toolkit that supports multiple domains such as Automatic Speech Recognition (ASR), Text to Speech generation (TTS), Speaker Recognition (SR), Diarization (SDR), Natural Language Processing (NLP), Neural Machine translation (NMT) and much more. NVIDIA RIVA has long been the toolkit that enables efficient deployment of NeMo models. In recent months, NeMo Megatron supports training and inference on large language models (upto 1 trillion parameters !).
