Restaurants stack every audio quality problem at once, and Deepgram is fixing it
Blog post from Deepgram
Restaurants present a challenging environment for voice agents due to the complex acoustic conditions created by multiple noise sources such as kitchen equipment, background chatter, and echo from hard surfaces, which can significantly lower the signal-to-noise ratio. This makes it difficult for voice models to accurately identify and process the primary speaker's voice among overlapping conversations, like a customer placing an order while a friend adds comments or a child interjects. Deepgram addresses these issues through techniques like primary speaker identification, echo cancellation, and hardware solutions such as carefully placed microphones and noise-reducing barriers. Their research emphasizes optimizing voice agents to function effectively in noisy environments, ensuring accurate order transcription by distinguishing between primary and non-primary voices and requiring agent confirmation for ambiguous inputs. This approach is backed by hardware like the HME Nexeo, which provides on-device audio processing to enhance quality in demanding conditions, differentiating Deepgram's solutions from those typically designed for quieter settings.
