Gowajee Thai Voice AI Agents and Speech API

Gowajee Co., Ltd. is a Bangkok-based enterprise voice AI company founded in 2023. Its team includes CEO Pisuth Huang, Chief AI Scientist Prof. Ekapol Chuangsuwanich, with a PhD from MIT, and CTO Pongsatorn Nitithammawoot. It argues that global voice AI platforms underserve Thai businesses because they are not built for the Thai language or market.

The platform is built on its own Thai-first speech-to-text and text-to-speech engines. On top of these, a no-code flow editor with drag-and-drop design, templates and chat-based editing lets non-technical teams build AI phone agents for inbound and outbound calls. Agents connect through SIP trunk, CRM and webhooks, with live call monitoring, human handoff and real-time post-call analytics. A low-latency streaming API exposes the speech engines to developers. Customers are Thai enterprises in financial services, logistics, retail, e-commerce and BPO.

• Thai-first STT and TTS: in-house speech recognition and synthesis tuned for Thai.
• No-code flow editor: drag-and-drop builder with templates, preview and chat-based editing.
• Call automation: inbound and outbound AI phone agents for collections, sales and service.
• Live monitoring and handoff: dashboard of active calls with human takeover controls.
• Post-call analytics: real-time AI analysis of call outcomes.
• Enterprise API: low-latency streaming API plus SIP trunk, CRM and webhook integrations.

Vietnamese companies operating in Thailand, such as consumer finance, logistics or retail firms, can run Thai-language collection, delivery confirmation and customer service calls. BPOs in Vietnam serving Thai clients can add Thai voice agents. Developers can use the Thai speech API for transcription of Thai-language calls.

Thai-native speech recognition and synthesis avoid the accuracy gaps of generic global engines. The website reports a 75% task completion rate, on par with human agents, and an average of 2 to 6 weeks from contract to go-live, with most pilots live in 2 to 4 weeks. The no-code editor lets operations teams change call flows without engineers, and the company states PDPA compliance and Thai data sovereignty.

Southeast Asian contact centers are adopting LLM voice agents, but accuracy depends on local-language speech models, which global vendors often lack. Thailand's PDPA and data sovereignty concerns favour local providers, a pattern that also applies to Vietnamese-language voice AI.

Gowajee Co., Ltd. was founded in 2023 and is based at Spaces Summer Hill on Sukhumvit Road, Bangkok. It showcased its Thai voicebot at Techsauce Summit 2025 and exhibited at Telecoms World Asia. The company states PDPA compliance and acts as a data processor for clients.
