What I need We want to build an AI system that: Can make outbound phone calls in Hungarian. Speaks in a natural human-like Hungarian voice. Asks a prepared questionnaire during the call. Can handle objections and continue the conversation (not just read text). Records and saves the answers in a structured way (Google Sheets / BigQuery). Automatically generates reports and charts (Google Looker Studio).
