Quick Start

Setup

2. Install CocoaPods

3. Import the Eagle-iOS pod by adding the following line to the project's Podfile:

pod 'Eagle-iOS'

4. Run the following from the project directory:

pod install

Usage

Speaker Enrollment

1. Create an instance of the profiler:

import Eagle

let accessKey: String = "${ACCESS_KEY}"
do {
    let eagleProfiler = try EagleProfiler(accessKey: accessKey)
} catch { }

2. Pass the enrollment audio data to the profiler until the enrollment percentage reaches 100%:

func get_next_enroll_audio_data() -> [Int16] {
    // ...
}

do {
    var percentage = 0.0
    var feedback: EagleProfilerEnrollFeedback?
    while (percentage < 100.0) {
        (percentage, feedback) = try eagleProfiler.enroll(pcm: get_next_enroll_audio_data())
    }
} catch { }

3. Export the speaker profile:

let speakerProfile = try eagleProfiler.export()

4. Release the resources acquired by the profiler:

eagleProfiler.delete()

Speaker Recognition

1. Create an instance of Eagle:

let eagle = Eagle(accessKey: accessKey, speakerProfile: speakerProfile)

2. Pass the incoming audio stream to Eagle:

func get_next_audio_frame() -> [Int16] {
    // ...
}

do {
    let profileScores = try eagle.process(pcm: get_next_audio_frame())
} catch { }

3. Release the resources acquired by Eagle:

eagle.delete()

Demo

For the Eagle iOS SDK, we offer a demo application that demonstrates how to use the speaker recognition engine on microphone audio.

Setup

Clone the Eagle repository from GitHub using HTTPS:

git clone --recurse-submodules https://github.com/Picovoice/eagle.git
