I have this code below that uses CHATGPT API in order to provide a response to the users input. Whilst the response is being printed out character by character it disables the users input. (This is just so you guys get an idea of what this code is.) I want to use AVSpeechSynthesizer in order to read the response aloud however I am not familiar with this and how to develop this. Please can you help me find a way using AVSpeechSynthesizer in order to read the response aloud. Here is the code:
import SwiftUI
import OpenAISwift
final class ViewModel: ObservableObject {
init() {}
private var client: OpenAISwift?
@Published var isChatting = false
func setup() {
client = OpenAISwift(authToken: "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")
}
func send(text: String, completion: @escaping (String) -> Void) {
client?.sendCompletion(with: text, maxTokens: 500, completionHandler: { result in
switch result {
case .success(let model):
let output = model.choices?.first?.text ?? ""
completion(output)
case .failure:
break
}
})
}
}
struct ContentView: View {
@ObservedObject var viewModel = ViewModel()
@State var text = ""
@State var models = [String]()
@State var textfieldEnabled = true
var body: some View {
VStack(alignment: .leading) {
ForEach(models, id: \.self) { string in
if string.starts(with: "User") {
Text(string)
.foregroundColor(.white)
.fontWeight(.bold)
} else {
Text(string)
.foregroundColor(.white)
.fontWeight(.bold)
}
}
Spacer()
HStack {
TextField("User Input", text: $text)
.disabled(!textfieldEnabled)
.padding(.bottom, 8) // Add padding to bottom of textfield
Button(action: {
send()
}) {
Image(systemName: "camera.filters")
}.font(.system(size: 32))
.disabled(!textfieldEnabled)
}
.padding(.bottom, 10)
Button {
//self.returnhomeFromConverter.toggle()
}label: {
Text("Return")
.fontWeight(.bold)
.foregroundColor(.white)
.frame(maxWidth: .infinity)
.padding(.vertical)
.background{
RoundedRectangle(cornerRadius: 12, style: .continuous)
.fill(.clear)
}
}
}
.preferredColorScheme(.dark)
.onAppear {
viewModel.setup()
}
.padding()
}
func send() {
guard !text.isEmpty && !viewModel.isChatting else {
return
}
viewModel.isChatting = true
models.append("User: \(text)")
textfieldEnabled = false
viewModel.send(text: text) { response in
DispatchQueue.main.async {
self.models.removeLast()
self.models.append("ChatGPT: ")
var index = response.startIndex
Timer.scheduledTimer(withTimeInterval: 0.05, repeats: true) { timer in
guard index < response.endIndex else {
timer.invalidate()
viewModel.isChatting = false
textfieldEnabled = true
return
}
self.models[self.models.count - 1] += "\(response[index])"
index = response.index(after: index)
}
}
}
text = ""
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
