Speculative Decoding vs Standard Autoregressive Decoding
Speculative Decoding uses a small draft model to predict multiple tokens verified by the large model. Standard Autoregressive Decoding generates tokens one at a time using the full model for each step. Speculative decoding offers significant speedup for real-time voice AI applications. For most businesses, the best approach is to evaluate both based on specific requirements — or consider AnveVoice, which combines voice AI with agentic website actions for a unified customer engagement platform.
