AeonVoice 0.1.7

AeonVoice

Managed .NET wrapper for the AeonVoice speech synthesis engine.

AeonVoice provides a simple C# API over the native AeonVoice runtime and returns PCM16 audio samples for playback or WAV encoding.

Package relationship

• AeonVoice (this package): managed API + interop bindings.
• AeonVoice.Native: native runtime libraries for supported RIDs.

AeonVoice depends on AeonVoice.Native.

Supported runtimes

Current packaged runtimes:

• linux-x64
• linux-arm64

linux-arm64 native assets are built with a Debian 11 (Bullseye-era) baseline to improve compatibility across older Linux ARM64 runtimes (including Raspberry Pi and other SBC/server distributions).

Install

dotnet add package AeonVoice

Quick start

using AeonVoice;

using var engine = new AeonVoiceEngine();

SynthesisResult result = engine.SynthesizeToPcm16(
    text: "Hello from AeonVoice",
    voiceProfile: "Leena");

result.SampleRate is the output sample rate.
result.Samples is signed 16-bit mono PCM.

Voice profiles (English female)

• Leena

Runtime data requirements

This package now includes a minimal runtime data set for Leena voice and English language resources.

By default, AeonVoiceEngine auto-detects packaged resources from the application output directory:

1. ./aeonvoice/data
2. ./aeonvoice/config

These files are copied automatically by NuGet build targets from AeonVoice.Native.

If you store resources elsewhere, you can override with constructor args:

using var engine = new AeonVoiceEngine(
    dataPath: "/custom/path/data",
    configPath: "/custom/path/config");

Or environment variables:

• AEONVOICE_DATA_PATH
• AEONVOICE_CONFIG_PATH

If resources are missing or you use a different voice pack, engine initialization will fail.

Troubleshooting

DllNotFoundException / native load failures

• Confirm your RID is supported (linux-x64 / linux-arm64).
• Confirm native assets are present from AeonVoice.Native.
• On Linux, verify dependency resolution for .so files.

Engine creation fails

• Verify aeonvoice/data and aeonvoice/config exist under your app output.
• Ensure selected voice profile exists in installed resources (Leena is bundled).
