Quick answer
A knowledge base for phone agents is a curated repository of business information that an AI can retrieve in real time during a live call. It allows the agent to answer customer questions, resolve issues, and execute tasks such as booking appointments or updating a CRM record.
Hallucinations occur when an LLM generates plausible but false or unverified data, which can erode trust and damage customer experience. Phone agents rely on accurate, up‑to‑date information because any misinformation can lead to compliance violations and revenue loss.
Voxovo AI mitigates hallucinations by combining a tightly integrated knowledge base with real‑time tool access and measurable latency scorecards. The platform ensures that every response is grounded in verified data before it is spoken aloud.
How Voxovo AI works on Voxovo
Presence Buffer is Voxovo’s first‑in‑class pre‑cached filler audio that plays whenever the LLM or a tool is still processing. This guarantees callers never experience dead air, reducing call abandonment and maintaining brand reputation.
Live Sheet and Live Calendar empower agents to pull or update data directly from Google Sheets, Google Calendar, and other first‑party systems during the call. This live integration eliminates the need for manual look‑ups and keeps the knowledge base in sync with real‑world events.
Voxovo 1.0 Speed delivers the lowest turn latency with fixed language and voice models, ideal for high‑volume, low‑complexity interactions. The Smart mode prioritizes accuracy over speed, while Ultra adds Gemini‑powered speech‑to‑speech for richer conversations. Each mode supports mid‑call knowledge search on Speed, Smart, or Custom pipelines.
Managed stacks offer turnkey performance, whereas Custom mode gives full control over STT, LLM, and TTS components. By choosing the appropriate mode, teams can balance latency, accuracy, and compliance requirements.
Implementation checklist
When evaluating competitors, it is essential to consider BYO numbers, dead‑air handling, agency tenancy, and mid‑call tool access. Voxovo’s differentiation lies in its Presence Buffer, Live Sheet/Calendar, and native multi‑carrier telephony integration.
Vapi focuses on developer APIs and lightweight assistants, providing flexible integration but lacking built‑in dead‑air mitigation and agency‑level tenancy. Its knowledge base relies on external search engines, which can introduce hallucination risk if not tightly coupled.
Retell emphasizes low‑latency telephony and offers real‑time speech conversion, but it does not provide the same level of live data integration or a structured knowledge base with built‑in accuracy checks. Their focus is more on the voice channel than on knowledge reliability.
