Quick answer
Deploying a bilingual English + Spanish voice agent is straightforward on Voxovo AI. The platform’s managed stack, presence buffer, and live‑data tools let you build an agent that speaks smoothly in both languages without extra coding.
Customers increasingly expect support in their native language, and bilingual agents improve first‑contact resolution and customer satisfaction. Voxovo’s architecture supports simultaneous language toggling, so a single assistant can answer in English or Spanish based on caller input or region.
At its core, Voxovo AI combines a telephony interface, a speech‑to‑text engine, a large language model, and a text‑to‑speech engine. For bilingual calls, you simply enable the desired language models in the assistant builder and select the appropriate TTS voice for each language.
How Voxovo AI works on Voxovo
Step 1: Connect your existing telephony provider—Twilio, Telnyx, Plivo, or Vonage—to the Voxovo dashboard. The platform never owns numbers, so you retain full control of your caller IDs and billing.
Step 2: In the Agent Builder, add a new assistant and configure two language settings: English (en‑US) and Spanish (es‑ES). You can set a default language and allow the agent to detect caller language automatically using the STT confidence threshold.
Step 3: Pick a pipeline mode. Voxovo 1.0 Speed offers the lowest turn latency for real‑time conversations, while Voxovo 1.0 Smart provides higher transcription accuracy if your use case tolerates a few milliseconds more delay. Both modes support multilingual models, so your agent can switch on the fly.
Step 4: Activate the Presence Buffer to pre‑cache filler audio. The buffer plays a short, natural‑sounding pause while the LLM processes the caller’s request, eliminating dead air that could frustrate bilingual callers.
Implementation checklist
Step 5: Enable Live Sheet and Live Calendar. These first‑party integrations let the agent pull or write data to Google Sheets or schedule appointments in Google Calendar without leaving the call, which is essential for bilingual agents that need to access bilingual customer records.
Step 6: Craft prompts that include language detection cues. For example, begin each prompt with a short instruction in the target language, and use a conditional block that switches the TTS voice and language flag based on the detected input.
Step 7: Test in the browser and via PSTN. Voxovo’s Test Live console lets you run a full end‑to‑end simulation; then use your real PSTN number to verify latency, voice quality, and the presence buffer in a real environment.
