There are many modules, so the coverage should be looked at separately.
The official warehouse lists ASR, VAD, LID and punctuation modules. The transliteration model is for Chinese, some dialects and accents, English and mixed expressions. The fact that the language recognition module covers more languages does not mean that every recognized language can be transcribed by the same transliteration model. When selecting, check by module rather than just excerpting the maximum number of languages.
The warehouse update record includes model releases in February 2026 and technical reports in March. This is an introduction to already-revealed models, not a new model announcement on the day this article was published. This article also does not retest the accuracy or acceleration data listed by the warehouse.
Long recordings need to be segmented first
The official FAQ states respectively: FireRedASR2-AED supports input up to 60 seconds, and problems may occur with longer inputs; FireRedASR2-LLM supports up to 40 seconds, and the behavior of longer inputs has not been tested. Users should arrange the process according to the selected version and current document, and cannot directly regard a meeting recording as a verified input.
ChinaOPC recommends retaining the original file number, starting and ending positions, and processing version for each segmented segment. When you need to rerun a certain paragraph, you can retrieve the corresponding audio; when merging the fragments back into the full text, you also need to check whether there are missing words or duplications at the boundaries. You cannot make up inaudible content out of thin air just to make the text read smoothly.
First select the materials that are most likely to be misheard in the business.
Test materials can include device names, product models, dialect expressions, and switching between Chinese and English. Compare the authorized recording with the manual draft to record misheard, omitted and uncertain positions. There is a big difference between reading quietly and the actual working environment. The two can be checked in groups to avoid directly pushing the performance of one environment to the other.
After sorting out the punctuation, you should also listen back to the key sentences. The position of the clause will affect the understanding of conditions and negative relationships; for matters that require subsequent execution, it is more reliable to retain the to-be-confirmed mark than to automatically modify it into a complete instruction.

A usable result can contain both organized text, audio location, and manual modification records. What customers care about is not only whether the words appear, but also whether the key expressions can be verified. The operating environment, dependencies and specific weight permissions are checked separately before deployment.
