Need help with implementing tts on iOS.

[Jopii]

Is there any tutorial or guide i should take a look to implement tts with sherpa-onnx into my iOS app? I'm pretty new on all of this.

Please follow

Remeber to read it carefully, especially the instructions about how to add esepak-ng-data to your xcode project.

I opened the xcode project file and added the necessary model files and runned the app succesfully on my iPhone 16, but when i try to generate audio it gives me this error.

I didn't modify the code, just added a new function to get a customized vits piper model, also defined the correct return for it:

func getTtsFor_es_vision_medium() -> SherpaOnnxOfflineTtsWrapper {
// Ruta al modelo ONNX (asegúrate de que el nombre coincida con tu archivo)
let model = getResource("es-vision-medium", "onnx")

// Archivo de tokens
let tokens = getResource("tokens", "txt")

// Ruta a los datos de espeak-ng (para la pronunciación)
let dataDir = resourceURL(to: "espeak-ng-data")

// Configuración del modelo VITS
let vits = sherpaOnnxOfflineTtsVitsModelConfig(
model: model, lexicon: "", tokens: tokens, dataDir: dataDir)
let modelConfig = sherpaOnnxOfflineTtsModelConfig(vits: vits)
var config = sherpaOnnxOfflineTtsConfig(model: modelConfig)

return SherpaOnnxOfflineTtsWrapper(config: &config)
}

As said before, please follow the instructions in the PR I posted.

Don't change any code, don't add any code, before you manage to run the tts demo.
