Paxa Labs and Amazon Transcribe for multilingual speech to text
A transcription API for Thai and other languages next to Amazon Transcribe, across Thai mixed with English, language support, how the transcript comes back, speakers, vocabulary, subtitles, and live transcription.
Amazon Transcribe lists Thai and Simplified Chinese for batch and streaming. Its multi-language identification transcribes each language when a speaker switches mid-conversation, and its batch jobs read each recording from an Amazon S3 bucket. Paxa STT Lite transcribes Thai, English, Mandarin, and other languages, and one request returns the transcript in its response. A Thai sentence that turns into English is written as it was spoken, with no setting. Paxa STT Lite is a Research preview. Requests bill at the published rate, and its transcript quality and options may change between releases.

What differs
| Dimension | Paxa Labs | Amazon Transcribe(opens in a new tab) |
|---|---|---|
| Thai with English inside it | A Thai sentence that switches into English is written as spoken, with no setting. Nothing is translated. | Multi-language identification transcribes each language a batch file contains, with th-TH, zh-CN, and en-US on its list. Redaction and custom language models do not work with it. |
| Languages | Thai, English, Mandarin, and other languages. Paxa STT Lite writes speech in the language spoken and detects that language itself. A BCP 47 hint corrects a recording it misreads. | Thai (th-TH) and Simplified Chinese (zh-CN) for batch and streaming. Their table lists no custom language model or redaction for either, and no Call Analytics for Thai. |
| Getting the transcript | One request with model paxa-stt-lite-v1-preview returns the transcript in its response, for recordings up to 120 minutes and 95 MiB. | A batch job reads the media file from an Amazon S3 bucket, up to 28,800 seconds and 2 GB per file. |
| Speaker turns | Speaker turns numbered from 0 in order of first appearance, on recordings up to 120 minutes, at no extra charge. | Up to 30 speakers, labeled spk_0 through spk_29. |
| Vocabulary | A vocabulary of up to 50 terms, in Thai or any other language, at no extra charge. | A custom vocabulary file of up to 50 Kb, created ahead of time in the same AWS Region as the job. It works with every supported language. |
| Subtitles | An SRT or WebVTT file in the same response. Every line break falls on a word boundary, Thai included. | WebVTT and SubRip files from a batch job, stored beside the transcript in Amazon S3. Numbering starts at 0 unless the request sets 1. |
| Live transcription | Paxa STT Lite Realtime streams over a WebSocket, reports when the user starts and stops talking, and sends one final transcript per turn. | Streaming over HTTP/2 or a WebSocket, in FLAC, Ogg Opus, or PCM, with 25 concurrent streams per Region by default. |

What does Research preview mean for Paxa STT Lite?
Requests bill at the published rate. Transcript quality and the option set may change between releases, and the changelog on our speech to text page records each change.
