## Text-to-Speech
|
||||
|
||||
We generated the same strings with to gerneate audio between 1s to ~300s in order to test the speed across a range of varying inputs on Pytorch CPU, MPS, and MLX pipeline, and compared it against the native Swift version with Core ML models.
|
||||
|
||||
Each pipeline warmed up the models by running through it once with pesudo inputs, and then comparing the raw inference time with the model already loaded. You can see that for the Core ML model, we traded lower memory and very slightly faster inference for longer initial warm-up.
|
||||
|
||||
Note that the Pytorch kokoro model in Pytorch has a memory leak issue: https://github.com/hexgrad/kokoro/issues/152

||||
|
||||
The following tests were ran on M4 Pro, 48GB RAM, Macbook Pro. If you have another device, please do try replicating it as well!

# eSpeak-NG Framework Packaging
|
||||
|
||||
FluidAudio bundles the eSpeak-NG phoneme resources so Kokoro can fall back to G2P lookups when the US lexicons don’t contain a word. The Core ML pipeline expects the resources under `Resources/espeak-ng/espeak-ng-data.bundle` with the canonical `voices/` directory inside.
|
||||
|
||||
## All Platforms (Primary Flow)
|
||||
- `TtsResourceDownloader.ensureEspeakDataBundle` first attempts to stage the packaged `espeak-ng-data.bundle` from SwiftPM resources (`Sources/FluidAudio/Resources/espeak-ng/`).
|
||||
- The bundle is copied to `~/.cache/fluidaudio/Models/kokoro/Resources/espeak-ng/`.
|
||||
- The `voices/` directory is validated after staging; if missing, `TTSError.downloadFailed` is raised.
|
||||
|
||||
## Fallback Behavior (macOS Only)
|
||||
- If the packaged bundle is unavailable, **macOS only** falls back to downloading `espeak-ng.zip` from HuggingFace and extracting it with `/usr/bin/unzip`.
|
||||
- **iOS/tvOS/watchOS** do not support fallback downloads and will throw `TTSError.downloadFailed` if the packaged bundle is missing.
|
||||
- For mobile platforms, ensure the packaged bundle is present in the Swift package resources before building.
|
||||
|
||||
## Best practices
|
||||
- Keep the `espeak-ng-data.bundle` (packaged copy) and the optional `espeak-ng.zip` fallback in sync with any updates to the Kokoro phoneme mapper.
|
||||
- If you customize the cache location, be sure the `Resources/espeak-ng/espeak-ng-data.bundle/voices/` directory is present before running TTS.
|
||||
- When testing on iOS, bundle the extracted resources with the app or seed the simulator cache in advance to avoid runtime failures.
|
||||
|
||||
## CocoaPods integration notes
|
||||
- The `ESpeakNG.xcframework` now includes support for iOS device (arm64), iOS Simulator (arm64 + x86_64), and macOS (arm64 + x86_64).
|
||||
- iOS Simulator support is provided via a stub framework that allows building and linking but returns failure values for ESpeakNG function calls.
|
||||
- Pod validation passes successfully with `pod lib lint FluidAudio.podspec --allow-warnings` for all platforms.
|
||||
- On iOS Simulator, ESpeakNG initialization will fail gracefully and phonemization requests will return `nil` due to the stub implementation.
|
||||
- Full ESpeakNG functionality is available on iOS device and macOS platforms.
|
||||
|
||||
## Licensing notes
|
||||
- eSpeak-NG is distributed under the GNU GPL v3 (or later). Both the core library and the `espeak-ng-data` voices inherit the same license.
|
||||
- The full license text now lives at `Licenses/ESpeakNG_LICENSE.txt`; ship this file (or the upstream `COPYING`) anywhere the framework is redistributed and surface it in your third-party notices UI.
|
||||
- If you republish the prebuilt `ESpeakNG.xcframework`, keep the license alongside the binary and ensure downstream consumers can obtain the corresponding source per GPL requirements.

# Text-To-Speech (TTS) Code Examples
|
||||
|
||||
> **⚠️ Beta:** The TTS system is currently in beta and only supports American English. Additional language support is planned for future releases.
|
||||
|
||||
Quick recipes for running the Kokoro synthesis stack.
|
||||
|
||||
## CLI quick start
|
||||
|
||||
```bash
|
||||
swift run fluidaudio tts "Welcome to FluidAudio text to speech" \
|
||||
--output ~/Desktop/demo.wav \
|
||||
--voice af_heart
|
||||
```
|
||||
|
||||
The first invocation downloads Kokoro models, phoneme dictionaries, and voice embeddings; later runs reuse the
|
||||
cached assets.
|
||||
|
||||
## Swift async usage
|
||||
|
||||
```swift
|
||||
import FluidAudio
|
||||
import Foundation
|
||||
|
||||
@main
|
||||
struct DemoTTS {
|
||||
static func main() async {
|
||||
guard #available(macOS 13.0, *) else {
|
||||
print("FluidAudio TTS requires macOS 13 or newer.")
|
||||
return
|
||||
}
|
||||
|
||||
let manager = TtSManager()
|
||||
|
||||
do {
|
||||
try await manager.initialize()
|
||||
let audioData = try await manager.synthesize(text: "Hello from FluidAudio!")
|
||||
|
||||
let outputURL = URL(fileURLWithPath: "/tmp/fluidaudio-demo.wav")
|
||||
try audioData.write(to: outputURL)
|
||||
print("Saved synthesized audio to: \(outputURL.path)")
|
||||
} catch {
|
||||
print("Synthesis failed: \(error)")
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Swap in `manager.initialize(models:)` when you want to preload only the long-form `.fifteenSecond` variant.
|
||||
|
||||
## Inspecting chunk metadata
|
||||
|
||||
```swift
|
||||
let manager = TtSManager()
|
||||
try await manager.initialize()
|
||||
|
||||
let detailed = try await manager.synthesizeDetailed(
|
||||
text: "FluidAudio can report chunk splits for you.",
|
||||
variantPreference: .fifteenSecond
|
||||
)
|
||||
|
||||
for chunk in detailed.chunks {
|
||||
print("Chunk #\(chunk.index) -> variant: \(chunk.variant), tokens: \(chunk.tokenCount)")
|
||||
print(" text: \(chunk.text)")
|
||||
}
|
||||
```
|
||||
|
||||
`KokoroSynthesizer.SynthesisResult` also exposes `diagnostics` for per-run variant and audio footprint totals.

## Text‑To‑Speech (TTS)
|
||||
|
||||
> **⚠️ Beta:** The TTS system is currently in beta and only supports American English. Additional language support is planned for future releases.
|
||||
|
||||
- Model: Kokoro (CoreML unified model)
|
||||
- Language: American English (beta)
|
||||
- G2P: Dictionary first, then eSpeak NG (CEspeakNG) for OOV words
|
||||
- Output: 24 kHz mono WAV
|
||||
|
||||
Requirements (macOS)
|
||||
Ensure eSpeak NG headers/libs are available via pkg-config (`espeak-ng`).
|
||||
https://github.com/espeak-ng/espeak-ng/tree/master
|
||||
|
||||
### Quick Start (CLI)
|
||||
|
||||
```bash
|
||||
# First run will download the Kokoro model and vocab
|
||||
swift run fluidaudio tts "Hello from FluidAudio." --auto-download --output out.wav
|
||||
|
||||
# Another example with punctuation and OOV handling
|
||||
swift run fluidaudio tts "Edge-cases: URLs like https://example.com and e-mail test@example.com." --output out2.wav
|
||||
```
|
||||
|
||||
Notes
|
||||
- The TTS pipeline uses a word→phoneme dictionary first; unknown words are phonemized with eSpeak NG (C API) and mapped to the model’s token set.
|
||||
- OOV words are printed with their IPA and mapped tokens for visibility during synthesis.
|
||||
- We do not prepend any “language token” to avoid leading vowel artifacts.
|
||||
|
||||
### Quick Start (Code)
|
||||
|
||||
```swift
|
||||
import FluidAudio
|
||||
|
||||
Task {
|
||||
do {
|
||||
let data = try await KokoroModel.synthesize(text: "Hello from FluidAudio.")
|
||||
try data.write(to: URL(fileURLWithPath: "out.wav"))
|
||||
} catch {
|
||||
print("TTS error: \(error)")
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Troubleshooting
|
||||
Build requires eSpeak NG headers/libs for the C API discoverable via pkg-config (`espeak-ng`).
|
||||
- If SwiftPM cannot find headers, build with explicit paths:
|
||||
- `swift build -Xcc -I/opt/homebrew/include -Xlinker -L/opt/homebrew/lib`
|
||||
- Dictionary and model assets are cached under `~/.cache/fluidaudio/Models/kokoro`.

|

When a message is supplied to espeak_synth, the request is buffered and espeak_synth returns. When the message is really processed, the callback function will be repetedly called.
|
||||
|
||||
|
||||
In RETRIEVAL mode, the callback function supplies to the calling program the audio data and an event list terminated by 0 (LIST_TERMINATED).
|
||||
|
||||
In PLAYBACK mode, the callback function is called as soon as an event happens.
|
||||
|
||||
For example suppose that the following message is supplied to espeak_Synth:
|
||||
"hello, hello."
|
||||
|
||||
|
||||
* Once processed in RETRIEVAL mode, it could lead to 3 calls of the callback function :
|
||||
|
||||
** Block 1:
|
||||
<audio data> +
|
||||
List of events: SENTENCE + WORD + LIST_TERMINATED
|
||||
|
||||
** Block 2:
|
||||
<audio data> +
|
||||
List of events: WORD + END + LIST_TERMINATED
|
||||
|
||||
** Block 3:
|
||||
no audio data
|
||||
List of events: MSG_TERMINATED + LIST_TERMINATED
|
||||
|
||||
|
||||
* Once processed in PLAYBACK mode, it could lead to 5 calls of the callback function:
|
||||
|
||||
** SENTENCE
|
||||
** WORD (call when the sounds are actually played)
|
||||
** WORD
|
||||
** END (call when the end of sentence is actually played.)
|
||||
** MSG_TERMINATED
|
||||
|
||||
|
||||
The MSG_TERMINATED event is the last event. It can inform the calling program to clear the user data related to the message.
|
||||
So if the synthesis must be stopped, the callback function is called for each pending message with the MSG_TERMINATED event.
|
||||
|
||||
A MARK event indicates a <mark> element in the text.
|
||||
A PLAY event indicates an <audio> element in the text, for which the calling program should play the named sound file.

a single byte which gives a "priority" number. The list of languages is terminated by an
|
||||
additional zero byte.
|
||||
|
||||
A language name consists of a language code, optionally followed by one or more qualifier (dialect)
|
||||
names separated by hyphens (eg. "en-uk"). A voice might, for example, have languages "en-uk" and
|
||||
"en". Even without "en" listed, voice would still be selected for the "en" language (because
|
||||
"en-uk" is related) but at a lower priority.
|
||||
|
||||
The priority byte indicates how the voice is preferred for the language. A low number indicates a
|
||||
more preferred voice, a higher number indicates a less preferred voice.
|
||||
|
||||
In (2), the "languages" field consists simply of a single (UTF8) language name, with no preceding
|
||||
priority byte.
