Improve decoding (#291) 
* whisper : prepare infra for new decoding strategies

* whisper : apply logit filters and compute logprobs

* whisper : add whisper_get_logits()

* whisper : separate self and cross attention memory

Initial step needed for supporting parallel decoders

* whisper : move probs_id buffer to whisper_context

* whisper : refactor kv cache into separate struct

* whisper : move self-attention kv cache to whisper_decoder

* whisper : wip decoding parameters + strategies

* whisper : wip decoding parameters + strategies (part 2)

* whisper : wip decoding parameters + strategies (part 3)

* whisper : wip decoding parameters + strategies (part 4)

* whisper : fix prompt_past update to not include prompt_init

* whisper : temperature + best_of support

* whisper : support for compression_ration_threshold

We actually use entropy, but it is similar

* command : fix example to use logits instead of obsolete probs

* whisper : handle empty sequence ranking

* whisper : add WHISPER_DEBUG + diagnostic prints + new main args

* whisper : minor fixes

* whisper : add beam-search support

* whisper : bug fix when there no previous context

* whisper : add comments

* stream : disable temperature fallback

For real-time processing, we always want a single decoder running at T=0

* whisper.swiftui : update example - fix paths + add empty folders

* whisper : rename whisper_init to whisper_init_from_file

* whisper : add whisper_init_from_buffer

* android : Delete local.properties

* android : load models directly from assets

* whisper : adding <stddef.h> needed for size_t + code style

Kevin Brothaler 91fc08c641 Build a vfpv4 library for armeabi-v7a and do runtime detection to select the right library 2022-12-22 16:47:54 +02:00
Kevin Brothaler e1432dd91a Check for both __ARM_NEON and __ARM_FEATURE_FMA so that the project can be compiled for armv7a. 
Android armeabi-v7a's NEON support doesn't support FMA unless configured with `-mfpu=neon-fp-armv8`, which would need runtime checks.
* Also removed ABI filter from Android project.

Georgi Gerganov f2df9bd768 stream : add "max_tokens" cli arg

Georgi Gerganov fb8d77f760 stream : add "audio_ctx" parameter 
Used to overwrite the audio context size of the Encoder.
For example, setting "audio_ctx = 512" will make it run about 3 times
faster, processing about 10s of audio, instead of 30s.

The transcription quality drops, but this can be used for real-time
streaming purposes where performance is important.

Georgi Gerganov 83c742f1a7 whisper : add option to speed up the audio tempo by x2 
Using a Phase Vocoder for speeding up the audio tempo by scaling down
the frequencies in the frequency domain.

This reduces the computation in the Encoder by a factor of 2.
The transcription accuracy is degraded, but for slow to normal speech -
it seems to be still very good.

I think this can find application for real-time transcription - i.e. the
"stream" example.
