Voice Agents are configurations that pair STT- LLM- TTS models to follow a set of instructions and do actions throughout the conversation. When working on creating voice agents you always run into the same problems. Latency all around, LLM bottelenecks, are STT good enough for your transcriptions? where are the voice models, the orchestration and the llm running ? Are they in region? Am I compliant with the current frameworks when running this voice agent? With SLNG regions we are bringing everyone the possibility to create production ready voice agents in all the regions we support. All voice agents running in our infrastructure are by default connected to our [execution layer](/concepts/execution-layer/overview), giving you a layer of optimization in every agent you create. You can start here [configuring your agent](/guides/get-started/create-a-project/create-agent) in SLNG.
