Thai transcription that solves word boundaries and tonal ambiguity
Thai script has no spaces between words, creating genuine ambiguity — ตากลม could segment as ตา+กลม ("eye" + "round") or ตาก+ลม ("to dry" + "wind"). Vowels can appear before, after, above, below, or surrounding the consonant they belong to (เกาะ places เ- before and -าะ after ก). Thai has five tones partly determined by consonant class, and register varies widely — the word for "eat" alone has three levels: กิน (informal), รับประทาน (formal), and เสวย (royal). Vocova's AI resolves these ambiguities from context, producing correctly segmented Thai text with natural readability.

Features
Intelligent word segmentation
Thai has no spaces between words, and word boundaries are often ambiguous even for native readers. The AI uses linguistic context to segment correctly — resolving cases like ตากลม where the meaning depends entirely on the segmentation.
Five-tone recognition
Thai's five tones (mid, low, falling, high, rising) change meaning completely — มา (mid: "come"), หมา (rising: "dog"), ม้า (high: "horse"). The AI distinguishes tonal patterns from acoustic features and consonant class context to select the right word.
Complex vowel positioning
Thai vowels don't simply follow their consonant — เ sits before, -า after, -ิ above, -ุ below, and compound vowels like เ-าะ surround the consonant. The AI outputs these in correct Unicode order, so vowels display in their proper visual positions.
Identify Thai speakers
Multiple speakers are automatically detected and labeled throughout the transcript, making interviews, meetings, and multi-host podcasts easy to follow.
Register-aware transcription
Thai varies dramatically by register — from casual speech using กิน, ไป, นอน to formal writing with รับประทาน, เดินทาง, พักผ่อน. The AI transcribes the register actually spoken rather than normalizing everything to formal Thai.
