Con Julius (pacchetto a riga di comando presente ma non istallato in synaptic-gestore pacchetti) è possibile trascrivere file mp3 in testo, almeno così mi è parso di capire.

Solo che non so come farlo funzionare (e se magari va con l'italiano).
--- poi ci sarebbe anche ---
DeepSpeech di Mozilla
anche questo a riga di comando?
Forse è meglio di Julius con l'italiano solo che non capisco come si installa in Ubuntu 18.04
Codice: Seleziona tutto
deepspeech [-h] --model MODEL [--lm [LM]] [--trie [TRIE]] --audio AUDIO
[--beam_width BEAM_WIDTH] [--lm_alpha LM_ALPHA]
[--lm_beta LM_BETA] [--version] [--extended] [--json]
Qui comunque ho postato la discussione che credo possa interessare anche a questa dove sto postando.
viewtopic.php?f=73&t=642287
È un argomento molto difficile (almeno per me) in cui ci sono poche informazioni (o non riesco a trovarne).
Salve, magari spiegare le differenze tra i 2 comandi.
Ciao
