Please, help to select a good model for French/streaming on smartphone

Hi all,
First congrats for this amazing project! Sherpa is really awesome.

But there is so many models, I am a little bit lost ... and maybe there is not so many model for my use case : streaming, 4Go RAM, French.
In order to be efficient in real time, I looked for transducer based models but I only found these ones for the French language;

• sherpa-onnx-nemo-fast-conformer-transducer-en-de-es-fr-14288.tar.bz2
• sherpa-onnx-nemo-fast-conformer-transducer-be-de-en-es-fr-hr-it-pl-ru-uk-20k.tar.bz2
• icefall-asr-multidataset-pruned_transducer_stateless7-2023-05-04.tar.bz2

And those models are probably to big to be deployed and used on A32....

So, does anyone know which model could be a good alternative to Kroko for the french language ? The targeted smartphone is typically Samsung A32 with RAM 4 Go.
I tried the "basic" zipformer from 2023 in the int8 format (sherpa-onnx-streaming-zipformer-fr-2023-04-14.tar.bz2) but I have a lot a mistakes in the transcriptions. And injecting hotwords will be not be sufficient to solve the kind of errors that I saw in the transcriptions.

Any help or suggestion is welcome
Thank you

Please try
https://k2-fsa.github.io/sherpa/onnx/pretrained_models/offline-transducer/nemo-transducer-models.html#sherpa-onnx-nemo-parakeet-tdt-0-6b-v3-int8-25-european-languages

APK for streaming ASR of this model can be found at https://k2-fsa.github.io/sherpa/onnx/android/apk-simulate-streaming-asr.html

(Search for tdt and v3)

Additionally, APKs with filenames containing _fr_ on the aforementioned page are also strong candidates.

Thank you @csukuangfj
The result with model parakeet tdt v3 is very impressive !!

Could you please tell if I can find the source code of the APK sample?
To make my prototype, I would like to start from this code to see how the loading of the model is configured and how the streaming of the microphone is while the model is an offline model. It would be great to have this example as support!

And is possible to use hotwords with kind of models (to help the engine du recognizer brand names, company names, references of equipments,etc.). if you think it's not useful for this model, let me know.

[EDIT]
Additional tests showed me that the model tends to switch to English even though I speak French (perhaps on the silences that swtich does elsewhere)
[EDIT]
And also often the last sentences are lost... I understand that it corrects the past sentences but on the other hand why sometimes certain parts of sentences disappear... very curious...
Any advice to overcome these concerns would be very appreciate.

honestly I love this Sherpa project, it’s incredible
Thank you very much for your help !!

And also often the last sentences are lost

Maybe that is caused by some bug in our code.

Thank you for your help
I'll look at all the links you gave me and hope I can get the model to work properly

For you information, I tried also:
sherpa-onnx-1.12.23-arm64-v8a-simulated_streaming_asr-en_de_es_fr-fast_conformer_ctc_14288.apk => not so good as parakeet in French (but I did not have the bug about the bug on disappearing sentences)
sherpa-onnx-1.12.23-arm64-v8a-simulated_streaming_asr-multi-funasr_nano_int8_2025_12_30.apk => do not load on my A32 (4Go RAM)
sherpa-onnx-1.12.23-arm64-v8a-simulated_streaming_asr-multi_lang-dolphin_base_ctc.apk => very strange but the transcription is done in a cyrillic language, not in French...

Thank you very much for your help!
I'm going to delve into the links you gave me
