Singapore banks face high customer expectations for fast,24/7 service.A DBS-sized bank(anonymized)deployed Instadesk's AI voice assistant to automate routine inquiries such as balance checks,credit card payments,and branch location lookups.Results after 9 months:call volume to human agents reduced by 60%,customer satisfaction increased by 28%,and the bank saved SGD 1.2 million annually.This case study details the bank's challenges,solution,and quantifiable outcomes,providing a roadmap for financial institutions across Southeast Asia.
Customer Background and Pain Points
The bank served 1.5 million retail customers and employed 300 call center agents.Its call center received 80,000 calls monthly,with 55%being routine inquiries:balance checks,recent transactions,credit card due date,branch hours,and fund transfer status.Average wait time was 6 minutes during peak hours(10 AM–2 PM and Monday mornings),and abandonment rates reached 25%.After-hours calls(8 PM–8 AM)went to voicemail,leading to lost customer opportunities and complaints.The bank needed an AI voice assistant that could support English,Mandarin,and Malay(Singapore's official languages),integrate with its core banking system(Silverlake),and handle up to 10,000 concurrent calls during peak periods without degrading performance.
The Solution:AI Voice Assistant for Banking
The bank deployed Instadesk's voice assistant integrated with its Silverlake core banking system.Key features included:
· Multilingual NLU(English,Mandarin,Malay)for natural call handling,trained on banking terminology like"account balance","transaction history","credit card due date",and"fund transfer status".
· Balance and transaction history:customers spoke"What is my balance?"or"Show me my last three transactions"and received real-time answers.
· Credit card payment due date and minimum payment amounts,integrated with the bank's card management system.
· Fund transfer status:customers could check if a transfer had completed,including interbank transfers(FAST)and cross-border remittances.
· Branch and ATM locator based on customer's current location(via number lookup or postal code).
· After-hours automation:all routine inquiries handled 24/7 without human intervention.
· Seamless escalation to human agents for complex issues(disputes,loan applications,fraud reporting),with full conversation context preserved.
Implementation and Results
Deployment took 4 weeks using Instadesk's banking template.The bank ran a pilot with 10,000 customers for 2 weeks,achieving 88%call containment.After full rollout,results after 9 months:
· Routine call volume to agents:Reduced by 60%(from 44,000 to 17,600 calls monthly),freeing agents for high-value work.
· Average wait time:Dropped from 6 minutes to 1.5 minutes(75%reduction)for calls that reached agents.
· Automation rate:70%of routine inquiries handled entirely by voice assistant without any agent involvement.
· Customer satisfaction:Increased from 72%to 90%(post-call surveys,5-point scale).
· Annual cost savings:SGD 1.2 million from reduced agent headcount(50 fewer agents needed),overtime reduction,and lower training costs.
· After-hours coverage:90%of after-hours calls resolved by voice assistant,eliminating voicemail and capturing after-hours customer requests.
· Language distribution:55%English,30%Mandarin,15%Malay–the assistant handled all with>95%intent recognition accuracy.
Key Lessons for Banks
· Multilingual support is essential for Singapore's diverse customer base;English-only bots will miss a large segment.
· Integration with core banking is critical for real-time balance and transaction data;batch updates are insufficient.
· Deploying a voice assistant for routine inquiries frees agents for high-value services like financial advisory,wealth management,and loan origination.
· High automation rates(70%+)are achievable with proper use case selection–start with balance and transaction inquiries,then add more complex intents.
· After-hours automation captures customers who would otherwise be lost to competitors with 24/7 support.
