We've selected replacement voices from ElevenLabs using their voice matching tool to find the closest match in tone and style. These voices are priced similarly to your existing voice.

**Engineer context carefully** - Use [context engineering](/tools/handoff#context-engineering) to control what conversation history is passed between assistants. As the context grows throughout the call, you may want to limit message history to reduce tokens, improve performance, and prevent context poisoning. Utilize [variable extraction](/tools/handoff#variable-extraction) to save information and generate summaries during a handoff to pass to other assistants.
