The Challenge
Speech-to-Text Accuracy
Incorrect text input corrupts downstream AI tools (intent, solutions), leading to misunderstandings and inaccurate resolutions for the operator.
Peak call volumes cause the AI databases to time out
Operators lose real-time assistance.
Tone of Operator Recommendations
Technical, or demanding language causes operator confusion and decreased confidence.
The Solution
We built an automated n8n pipeline that leverages Google Speech‑to‑Text for accurate transcription and Google Gemini for real‑time call summaries, action items, and operator‑friendly recommendations.
-
Google outperformed ElevenLabs in our tests.
-
In order to avoid timeouts of the AI tools, we had to separate the tasks into multiple steps. One-by-one execution helped to mitigate the problem.
-
The tone of languages of the AI recommendations to the phone call operators proved to be delicate and it required extra attention.
