Horrible inference results using the english pretrained model

Hi all,

I would like to test DeepSpeech fo transcript an audio from youtube.
I have converted the youtube file (https://www.youtube.com/watch?v=MiebCHmiszs) to mp3 and then form mp3 to wav (16000 hz).
I have used this commend to transcript

deepspeech --model test/deepspeech-0.9.1-models.pbmm --scorer test/deepspeech-0.9.1-models.scorer --audio test/audio/how-to-speak-english-fast-and-understand-natives-part-i.wav >> text_file_test.txt

the inference result is : “on meteorites foretopmast antanaclasis preparation toleration was to prove him a guerdon which says homesteaded you a suit than satiate or rooster or someone on missus harvester for on some charms the confraternities nonentities the goldbeater and techeechee entertainers to so you can do the same large on sapermillemente harcourt steamers reverberated operations there sundered to to mortonstown entered on so to arboriculture moreland to warburton and to you for a monopolist the murderer initiation to inoculate the donation superficialities to someone and shorefront unfortunates to torteval words pomegranates torontonians colander coerciveness that permeates restoratives preconisation foresters demanded to your potentate than there finistere thereunto animated trastevere belathered warminster for in the odometer from de earthenware sonatas or dodecatheon is heather orchaesis word to worcester to emissaries horse for added tetherdown on shootin creations the foreman ominously treasuretrove ear and the gardener to reverence the reports are torturing me on the mat oroondates entertainment costs and morning surely aristophanes anacoluthon should force murder spenersbergers so toadeaters sustenances perturbations a murder over sir which has power to timotheus the elocutionist warehouse or wanderer saw her greater than erroneously to or sentimental to the departure to go mad sir to rossiter seven shamefastness potentiometers peter promises to do and etherealise there than there that the barber and you toinette to undeceive the teotuctli secured the warehouse charlotte tetrabranchiata were interrogated nonsuited on additional locomotive emotions all you for to the escort orspittle seventeen o notorious or were austerities to yalahao starkweather foretaste heracleitean panathenaea or canonisation this rather teetotaler are orontobates you wore sobersides poormaster assured”

Any idea please ?

Generally, the model isn’t that good with fast speech. This could be the reason, but there were some reports that the 0.9 model might be a bit worse for clean speech. Could you try the 0.8 model on the file. Formats are compatible, so can just download the model and check.
