Occasionally Im seeing an index out of range
crash on the segmentLogProbs[index]
after a long period of silence. https://github.com/argmaxinc/WhisperKit/blob/main/Sources/WhisperKit/Core/TextDecoder.swift#L518-L521
Swift/ContiguousArrayBuffer.swift:600: Fatal error: Index out of range
Two ways I could see guarding against this:
segmentLogProbs
count.for (token, logProb) in zip(segmentTokens, segmentLogProbs) {
tokenProbs.append([token: logProb])
}
for (index, token) in segmentTokens.enumerated() {
if index < segmentLogProbs.count {
tokenProbs.append([token: segmentLogProbs[index]])
}
}
Happy to PR either one but unsure if Im missing a reason for this being as is.
Hi folks, just wanted to check in and ask what would be entailed in adding support for older mac versions, such as 13.0?
Hey guys! This looks great, unfortunately I'm having issues loading the models (both in my own code and the sample app)
I'm running this on an M1 Macbook Pro.
Many of the models don't load at all, even when given enough time (the progress bar usually gets stuck around specialization)
I've tried to download the models and manually use it as well, but I'm having trouble loading them as well.
Failed to read model package at file:///Users/puravmanot/Developer/Projects/WhisperTesting/WhisperTesting/whisper_large_v3_turbo. Error: A valid manifest does not exist at path: /Users/puravmanot/Developer/Projects/WhisperTesting/WhisperTesting/whisper_large_v3_turbo/Manifest.json
It also gets stuck sometimes while loading a pre-downloaded model
[WhisperKit] Loading models...
This can be done with logit filters on the first loop, similar to detecting language. However, this cannot be used when we are using a prefill prompt (i.e. forced decoder tokens) so that will need special handling. Ideally, there'd be an option to ignore the prefill prompt for the first decoder loop to detect no speech, which costs 1 extra loop but may allow skipping the entire window if developers are expecting some long stretches of silence in their input audio.

Language detection here should be fairly simple with logits filters now, it will entail a single decoder pass and sample just the language tokens. However, this cannot be used when we are using a prefill prompt (i.e. forced decoder tokens) so that will need special handling.

Thank you for your WORK!!!
I'm not a MacOS developer, but a user. I want to know if it's possible to use the computer's audio output in Stream, not just the microphone. The scenario is similar to simultaneous interpretation in meetings.
I look forward to your reply, thank you again!!!
When using Swift CLI example, followed the exact commands mentioned, getting above error:
Chip: Apple M3 Max
OS: 14.3.1
Xcode: Version 15.2
Apple Swift version: 5.9.2
import SwiftUI
import WhisperKit
@main
struct WhisperKitApp: App {
init() {
Task {
do {
let pipe = try? await WhisperKit()
let transcription = try? await pipe!.transcribe(audioPath: "Audio/output-lang.wav")?.text
print(transcription)
} catch {
print("Error: \(error)")
}
}
}
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
Then I get an error : Cannot call value of non-function type 'module<WhisperKit>'
What should I do to solve this problem? tks.
It would be great if certain patterns in the newly added word timestamps (#38 ) can be leveraged to reduce the incidence rate of hallucinations. This change will require comprehensive re-evaluation of the models since accurate words could also have zero-length based on inaccurate word timestamps.
Hey folks! I'm trying to use the CLI, but it fails to load models:

➜ whisperkit git:(main) make download-models
Downloading compressed models...
Repository exists, pulling latest changes...
HEAD is now at 07ea546 Create config.json
It would be worth adding support for ReactNative apps using Native Modules and expose Swift APIs to JS.
Currently when using the default WhisperKit flow of auto downloading models on transcribe, an internet connection is required even if models have already been downloaded in the past due to swift-transformers fetching the filenames here.
This is a bit limiting, as e.g. @pveugen was on a train with poor internet and couldn't transcribe audio even after downloading the model in the past (after #80 it would throw an error instead of crashing). I think we could get around this by manually downloading and specifying the path in setupModels modelFolder:
, but it would be nice if there was a way to avoid this HTTP get by default.

Hey! Thanks for making WhisperKit!
I hope I did not miss it in the documentation. But is it possible to provide a local URL to the model for the WhisperKit instead of relying on its internal mechanism to load the model? Inside my app I already have a nice UI that allows to download, suspend, and cancel download progress so would be nice if I could then feed WhisperKit with the local URL.
If there is no such functionality but you are considering adding it - I might try to help by making a PR.
Thanks.
Timestamp rules are helpful to more consistently find reliable timestamps during decoding.
Important note: We have already brought over some of this logic into the SegmentSeeker
which runs at the end of a full decode loop to generate the segments. This feature will need to detangle any repeated logic between them.
Openai implementation: https://github.com/openai/whisper/blob/ba3f3cd54b0e5b8ce1ab3de13e32122d0d5f98ab/whisper/decoding.py#L441-L505
The CLI executable should be able to stream directly from the microphone, similar to the WhisperAX example app. This enables use cases outside of an Xcode project.
WhisperAX streaming code:
WhisperKit/Examples/WhisperAX/WhisperAX/Views/ContentView.swift
Lines 997 to 1127 in 228630c
From what I understood there are some limitations and degradations to the model quality but it would still be nice to be able to support users on Ventura (and iOS 16)
I'm trying the demo app on a MacBook Pro with Apple M1 Pro and 16 GB memory. The large-v3_turbo_1049MB
model has been specializing for more than 30 minutes, but aned
is still running and using a whole performance core. Have you guys tested the loading time on different devices?
Hi,
Is speaker diarization planned (espec. in realtime)?
Thx!
It would be great if the first text token's logprob can be used to discard a transcription draft as failed and start over. Start over could mean either falling back to a higher temperature sampling or updating the audio buffer for streaming use cases.
WhisperKit/Sources/WhisperKit/Core/AudioProcessor.swift
Lines 197 to 217 in fed90c7
Creating an AVAudioPCMBuffer
for the whole input audio buffer can easily surpass iOS memory limits.
Attempting to transcribe a 44100hz, 2 channel, ~1hr long video crashes on iOS due to running out of memory. It would be nice if instead of reading all the input audio into a buffer at once and converting, the audio was read and converted in chunks to reduce the memory usage.
Another less common issue that would be solved by chunking the audio is that AVAudioPCMBuffer has a max size of UInt32.max, which can be hit when transcribing a 1-2hr, 16 channel, 44100hz audio file. This is a fairly typical audio file for a podcast recorded with a RODECaster Pro.
It would be great to start collecting reproducible performance benchmarks for supported hardware (e.g. A14+ and M1+). This should be a self-contained function that uses openai/whisper-base
by default and optionally other versions that the benchmark submitter selects. Benchmarks should run on a standard set of audio files and reports should be in a digestible and shareable format:
Psuedo-code may look like this:
jfk.wav
for short-form, ted_60.wav
and a sample clip from earnings22
for long-form transcriptions)Open ASR leaderboard benchmarks: https://github.com/huggingface/open_asr_leaderboard
Nice script for collecting environment info: https://github.com/pytorch/pytorch/blob/main/torch/utils/collect_env.py
Models are taking really good time to download. If the WiFI is OFF for a second it gets struck - it would be great if the example has two more options - Delete and Retry.
Hey guys, great work on the project and nice job with the word level timestamps recently!
Noticed that the package says the minimum target was recently changed to iOS 16 per https://github.com/argmaxinc/WhisperKit/blob/main/Package.swift, which is great.
What would be involved in bringing this down to iOS 15?
The goal is to leverage the high-quality word-level timestamps added in #38 as anchors to reliably seek the audio buffer forward at a higher frequency compared to current behavior:
<|endoftext|>
is generated or max_tokens
tokens are generated.It looks like the model is deleted when I use FIleManager removeAt method but when I re-run the project the deleted model appears again.
FileManager.default.removeItem(at: URL.init(string: "file://" + "(path)")!)
Beam search on CoreML will require some model changes to work according to the reference implementation. This is mainly due to CoreML static shapes requiring a new model for each possible beam_size
. We have some plans to deal with this so will keep this issue here for tracking purposes.
Openai implementation: https://github.com/openai/whisper/blob/ba3f3cd54b0e5b8ce1ab3de13e32122d0d5f98ab/whisper/decoding.py#L301-L404
need it for real-time stuff like: https://arxiv.org/pdf/2307.14743.pdf
p.s. great project!
Does it have a duration limit? I remember that Whisper limits the input file to 30 seconds, but when I tested it on macOS, the app could handle much longer duration audio files. Do you have to chunk the audio files before transcription?
trash
, used in the following make rule, is not part of a default macOS setup.
clean-package-caches:
@trash ~/Library/Caches/org.swift.swiftpm/repositories
@trash ~/Library/Developer/Xcode/DerivedData
I see three options to address this:
rm
instead, and delete immediatelymv
, and move the files to the user's trash in ~/.Trash
(only works properly if the files are in the local disk; for external hard drives trashes are at /Volumes/NAME_OF_EXTERNAL/.Trashes/USER_ID/
, and to handle these cases probably better go with option 3)trash
using Homebrew in the setup
rule.I am getting this error when trying to start WhisperKit in any simulator. Can someone say what could it be and how to fix?

Hey there!
First off, thanks so much for building this awesome library! Its a total pleasure to use and works great. Looking forward to the Metal
update. In the meantime, I was curious if you all would accept a PR to allow for AVCaptureSession
to be used in the AudioProcessor
class instead of AVAudioEngine
.
I was thinking of creating a way to pass in a new setupEngine function that allowed for the captureOutput
delegate to be used in place of the installTap
function. The reason I want to do this is it makes it easier to change the microphone in app instead of relying on the system default.
AudioProcessor
? If so, Im happy to come up with a clean interface proposal.AudioProcessor
class and provide an alternate setupEngine
function?Like OpenAI's Whisper, is it possible to pass a text prompt which could be used to improve the quality of the transcript?

the advantage of this project is that it uses CoreML for a performance gain, so showing benchmarks would solidify how much this advantage is
Needed for benchmarking the streaming functionality, as well as generally testing it's accuracy and performance. A simple loop can be made to read a file in incremental n
second chunks, where the audio length increases by n
seconds each loop, and the transcription is appended as the audio size increases.
the example is unable to run on iphone 11 pro.
(The example is running good on Mac m1 max )

would be great
I have problem being able to develop and run with this sadly.
I am running a AMD cpu windows 11 pc. I am using vmware to get MacOS, however I am not able to run any MacOS version after 12, due to amd cpu not supporting this. This in turn means that I cannot run the later versions of xcode that support swift 5.9.
Would you ever considering backporting some of this functionality for previous versions of swift?
When filtering out special tokens in addWordTimestamps, word timings that contain a timing token followed by a hyphen aren't filtered out correctly. WordTiming.tokens
correctly contains just [532]
, but WordTiming.word
is "<|0.00|> -"
. This seems to occur most when multiple people are talking over each other in a recording, I guess it's Whisper's way of trying to label speakers.
