MS-ensemble-speech-recognition
No estimate
No hardware requirements for this model
The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.
On record
Full specification
Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

What the numbers mean
Background
MS-ensemble-speech-recognition was published by Microsoft, in United States of America, in September 2016. The organisation is categorised as industry.
It works in Speech, and is recorded as doing speech recognition (ASR).
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
What went into building it
Around 11,140,000,000 tokens went into training it.
Its inclusion criterion is sOTA improvement.
Answers
MS-ensemble-speech-recognition — common questions
What is MS-ensemble-speech-recognition used for?
MS-ensemble-speech-recognition works in Speech, and is recorded as handling speech recognition (ASR). These are the areas it was designed around; they describe intent rather than a hard boundary.
What GPU do I need to run MS-ensemble-speech-recognition?
None. MS-ensemble-speech-recognition is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.
Is MS-ensemble-speech-recognition open source?
No. MS-ensemble-speech-recognition has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does MS-ensemble-speech-recognition have?
MS-ensemble-speech-recognition has 3.2B parameters. Large ensemble CNNs: 85000000 + 38000000 + 65000000 = 188000000 = 188M LSTMs: 40 / 140 input - 6*512 layers - 9000 / 27000 output 4*(140+512)*512 + 5*4*(512+512)*512 + 4*(512+27000)*27000=2983117056 LM: 1000*1000 = 1000000 + Embedding Total: 1000000+2983117056+188000000=3172117056 (underestimate because it doesn't account for embeddings). That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.
Who created MS-ensemble-speech-recognition?
MS-ensemble-speech-recognition was published by Microsoft, based in United States of America, categorised as industry.
When was MS-ensemble-speech-recognition released?
MS-ensemble-speech-recognition was published in September 2016. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
The other direction
Looking at it from the other side?
This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
