Deployment & First-Person Implementation Narrative
Pichai S.,Operations Lead at ThaiLogistics:
"We piloted the Thai voice bot on 10% of incoming calls for two weeks.The first challenge was accent variability–Isaan and Southern Thai accents confused the ASR.Our Instadesk engineer collected 2,000 regional accent samples and fine-tuned the model in five days.By week three,word error rate dropped from 19%to 11%."
Deployment steps:
· Week 1: Pilot on 10% of calls–order status and delivery ETA intents only
· Week 2: Added return request and address change intents;expanded to 30%of calls
· Week 3: Fine-tuned ASR on regional Thai accents;integrated with existing CRM(Zoho)
· Week 4: Full rollout to 100%of calls;agent dashboard with escalation workflow

|---|---|---|
| Thai (Central, Bangkok) | 8.2% | 6.5% |
| Thai (Isaan / Northern) | 19.4% | 11.3% |

*Test set:5,000 utterances per category;SNR 15-25 dB;mobile and landline.*
NLU Intent Parsing Accuracy(Top 6 Intents)
| Intent | Sample Size | Accuracy (F1) |
|---|---|---|
| Order status inquiry | 8,500 | 94.2% |
| Delivery ETA request | 6,200 | 92.8% |

Failure Modes & Mitigation Strategies
| Failure Mode | Real-World Example | Mitigation |
|---|---|---|
| ASR error (accent/background noise) | Southern Thai misheard "ส่งของ" (send parcel) as "ส่งโทรศัพท์" (send phone) | Confidence threshold (0.70). Bot asks: "Did you say parcel or phone?" (2-retry limit) |
| Intent ambiguity | Customer says "I want to change" | Slot-filling: "Are you changing address, order, or payment?" |
| Out-of-scope request | Customer asks about product warranty | Graceful escalation to human agent with context preserved |
| Mid-utterance interruption | Customer interrupts bot's response | Bot stops speaking, resets ASR buffer, re-evaluates intent |
Security,Privacy & Compliance(Thailand Focus)
| Area | Implementation |
|---|---|
| Encryption in transit | TLS 1.3 for SIP signaling; SRTP (AES-128) for media streams |
