* Verify that audio is clean after VAD segmentationyum2024-02-05
| | | | | | | | Indeed it is. Bumped up the default max segment length to decrease error. Also add mic presets for beyond (the vr headset) and motu (my mic interface).
* Revert "Begin experimenting with flash-attention"yum2024-01-08
| | | | This reverts commit 921b92a69f36502dc5eefd14ba3487c1bb49bb9d.
* Fix font rendering ddx/ddy logicyum2024-01-08

* Begin experimenting with flash-attentionyum2023-12-13
| | | | | | | | | | | Seems much faster than faster-whisper. There are two issues: * Requires NVIDIA 3000 series or higher. * Incompatible with faster-whisper dependencies. So it seems like we'll either need to toggle between two sets of dependencies at runtime or have two environments.
* Decrease OSC sync rate from 5 Hz to 3 Hzv0.17.0yum2023-12-08
| | | | Paging is now slower but more reliable.
* Add distilled whisper large-v2 modelyum2023-12-08
|
* Add distilled whisper-medium modelyum2023-11-07
| | | | | | I converted distil-whisper-medium.en to CTranslate2 format and uploaded it to huggingface. This model is exceptionally fast and light compared to the non-distilled version, at the cost of some accuracy.
* Transcripts preceding long pauses now dropv0.16.0yum2023-10-05
| | | | | | | | | | | | | | | | | | When hot-miking into the built-in chatbox, there are sometimes long pauses in conversation. After these pauses, it's undesirable to show the transcript generate before the pause. This feature makes it so that those transcripts can be dropped. Also: * Limit number of segments sent to browser source to 10. Allow this to grow up to 10 segments before dropping the first 5 segments. * Silence warnings generated by `install_in_venv`, used by e.g. translation codepath. * Enable audio normalization to improve accuracy when speaking softly, at the cost of some accuracy when speaking normally. Credit: user endo0269 on Discord suggested this feature.
* Reimplement BrowserSource as a StreamingPluginyum2023-09-18
| | | | | | | | | BrowserSource now fades text out continuously over time. TODO * Delete C++ webserver, browsersource, transcript code * Add UI for text age fading
* Add UI for process priorityyum2023-09-17
| | | | Default is normal prio.
* Bugfixesv0.15.4yum2023-09-16
| | | | | | | * uwu filter no longer adds extra whitespace before/after segments. This would defeat commit logic. * disabling phonemes works again - path to prefab was being quoted twice, breaking the codepath.
* General cleanupv0.15.3yum2023-09-13
| | | | Remove unused proxy code, curl, and images.
* Bugfix: list input devices works againyum2023-09-12
| | | | Oops :)
* Update demo in READMEyum2023-09-11
|
* Pin huggingface_hub to 0.16.4v0.15.2yum2023-09-11
| | | | | | | | | 0.17.x are breaking faster_whisper's ability to download models. Also: * Start using frozen requirements.txt. * Conditionally install torch & legacy whisper only when doing mechanical optimization.
* Introduce notion of PresentationFilteryum2023-09-10
| | | | | | | | | | | | | ... and restructure RemoveTrailingPeriod as a filter instead of as a plugin. Plugins have the power to change transcription data as it comes along, but don't have access to the entire transcript. Filters have access to the entire transcript but can't durably change it. TODO * This does not work with data passed through OSC
* Fix paging bugv0.15.1yum2023-09-10
| | | | | OSC was paging using incorrect board resolution. Use cfg to provide this data.
* Bugfix: eliminate dead-end in certain animator layersyum2023-09-10
| | | | | | | | Because the custom chatbox doesn't necessarily have an even multiple of `sync_params` character slots, some layers in the animator write N character slots while others write N-1. In the layers with only N-1 slots, they need something to do while slot N is being selected. This patch creates a return-home transition in that case.
* Users can now choose custom chatbox texture size in UIyum2023-09-10
|
* Fix local audio indicatorsv0.15.0yum2023-09-10
|
* Check in vad.py and delete transcribe.pyyum2023-09-10
| | | | | | | Oops, I meant to check this in a while back. Since transcribe_v2.py now has feature parity with transcribe.py, delete the old code.
* Add plugin interfaceyum2023-09-10
| | | | | | ... and use it to implement translation and text filters. Also fix display of non-English characters in browser src.
* Bugfix: only cap display of transcript at 4K charsyum2023-09-10
| | | | | | | | Actually retain the whole transcript to avoid breaking the OSC pager. Also constrain the UI buffer size by characters instead of lines. Since some lines can be massive and others short, characters are a better way of consistently keeping the UI memory in check.
* Add UI for transcription loop delayyum2023-09-10
| | | | | | | | Allows users to directly modulate the performance-latency tradeoff. Also: * Bump up UI buffer to 1k lines. * Fix browser source reset. It now also resets preview text.
* Browser source now shows preview text as slightly transparentyum2023-09-09
| | | | Improves viewer experience.
* Add UI for max speech durationyum2023-09-09
| | | | | Also fix bug when not using previews. Audio buffer no longer grows without bound while there's no speech.
* Constrain log file, UI text field, and transcript sizesyum2023-09-09
| | | | | | | | | Log file is constrained to 1 MB and UI to 100-200 lines. 1k lines is too high to keep the UI from lagging. Transcript is constrained to 4k characters. Also put a 5 ms sleep in the transcription hot path.
* Constrain UI text buffers to 1000 linesyum2023-09-09
| | | | This keeps memory usage from growing without bound.
* Make min silence duration configurable in UIyum2023-09-09
|
* Add `lock at spawn` optionyum2023-09-09
| | | | | | I find it kind of annoying when people wave around a big chatbox so I added the option to have the chatbox be locked in worldspace whenever it's visible. This defaults to on and can be disabled.
* Bugfix: fix preview text enable/disable in browser sourceyum2023-09-09
|
* Bugfix: fix process leak in PythonWrapper::InvokeCommandWithArgsyum2023-09-09
| | | | | | | | | | | | | It now waits up to 10 seconds for a graceful exit and falls back on the equivalent of a SIGKILL. The caller is assumed to have signaled to the process through `in_cb` that an exit is desired. Also: * Fix graceful exit path of transcribe_v2.py. * Add toggle to enable/disable preview text. It is enabled by default. * Constrain transcription temperature to 0.0. This keeps latency more predictable at the cost of some accuracy.
* Bugfix: non-text OSC messages wait for sync windowyum2023-09-08
| | | | This makes them more reliable.
* Bugfix: text data now pages correctlyyum2023-09-08
| | | | | | The non-text OSC messages were paging in too close to the text OSC messages, breaking the whole system. Now the non-text OSC messages bump back the time at which text OSC messages can begin being sent.
* Only transcribe if VAD detects somethingyum2023-09-08
| | | | | | | | | | | | Also: * DiskStream starts returning silence when out of data instead of just stopping. * Filter out Whisper segments with high `no_speech_prob` and low `avg_logprob`. * Add `saveAudio` function, useful for debugging. * Tune vad silence cutoff to 250 ms. This is pretty accurate in benchmarks.
* Add keyboard controls to transcribe_v2.pyyum2023-09-08
| | | | | | | Also parameterize `min_silence_duration_ms` in AudioSegmenter. I suspect that for conversational speech, segmenting closer to 500 ms (rather than the 2000ms default) is a better tradeoff between accuracy and compute efficiency.
* Drop transcription queueyum2023-09-07
| | | | No longer needed.
* Switch to VadCommitteryum2023-09-07
| | | | | | | | FuzzyRepeatCommitter was approximating this behavior in the best-performing configuration, so switch to it in earnest. This committer simply commits audio once we detect a long enough gap in speech. That's it!
* Put OSC logic into its own threadyum2023-09-05
| | | | | | | | | | | | | | | | | | This logic is highly IO bound *and* latency critical so it makes sense to put it into its own thread. Also: * Collector::drop* methods return the dropped audio. Committer includes that audio in commits. Transcription thread holds onto it. When the user segments their speech with a button press, the transcription thread sends the entire combined audio of all commits over to Whisper to be transcribed. This allows us to recover from errors introduced by segmentation. * Remove unused animator params * Fix issue where clearing the board doesn't completely reset STT state TODO: * Coalescing does not occur for in-place updates. It should.
* Wire transcribe_v2.py into GUIyum2023-09-03
| | | | | | | | Also: * Enable SO_REUSEADDR on browser src socket * Temporarily add evaluation dependencies to requirements.txt * Fix browser src. It's now looking for a prefix that the python app actually uses.
* Add threads to transcribe_v2.pyyum2023-09-03
| | | | | | | | | | | | Four threads: * Main thread * Transcription (mic -> collector -> whisper -> committer -> pager) * VR input * Keyboard input Also: * add OscPager class to encapsulate all OSC interactions. * bump `last_n_must_match` from 2 to 3 to reduce hallucinations
* Apply subtle compression to audio before transcribingyum2023-09-03
| | | | This has a slight positive effect on my benchmark.
* Experiment with Collector filtersyum2023-09-03
| | | | | | | | | | | | | | | | | | | | | | Try adding two filters on top of the usual AudioCollector: * Minimum length preservation: never report fewer than N seconds worth of audio data. Pad with silence as needed. * Volume normalizing: normalize audio volume. Using my benchmark of 30-second audio clips from 3 speakers (lower is better): length enf + norm = 87.118 nothing = 90.917 norm = 94.538 length = 111.402 Both together are a slight improvement, but independently degrade the result by a lot. I also observed more hallucinations in a conversational pattern when using them vs. not. So I'll phase them out. I'm still curious about *compression* as opposed to normalization.
* Begin rewriting transcribe.pyyum2023-09-02
| | | | | | | | | | A set of proper interfaces is called for. See #dev-update-spam in discord for drawing of design. Also add code to mechanically optimize committer parameters using an audio file. Not perfectly repeatable since it depends on the performance characteristics of the machine, but prob better than what we had before (nothing).
* Fix reference to deprecated symbolv0.14.1yum2023-09-01
|
* Bugfix: app no longer hangs if closed while transcribingyum2023-09-01
| | | | | Fix how OnExit callback is wired into GUI. Also make it exit Unity process, if that's going on.
* Various cleanupyum2023-09-01
|
* Check in app_config.py, remove_audio_source.pyyum2023-09-01
| | | | Oops, I meant to check these in earlier!
* Add `Enable phonemes` toggle to radial menuyum2023-09-01
| | | | | | | | | | Also: * Fully scrub AudioSource references from prefab when not using phonemes. * Disable net sync on phoneme params when not using them. When not synced, they don't count against the total memory limit. * Use config file in generate_params.py
* Add Unity panel toggle for phonemes (in-game audio indicator)yum2023-09-01
| | | | If not set, the prefab will have its audio sources removed.
