Pull request overview

Updates OVMS audio-related documentation and demos to reflect current recommended text-to-speech (Kokoro) and expanded speech-to-text examples (Whisper + Qwen ASR) using the OpenAI-compatible /v3/audio/* endpoints.

Changes:

• Switches TTS documentation/examples from SpeechT5 to Kokoro, including voice usage in request examples.
• Expands the audio demo to include Qwen ASR alongside Whisper and reorganizes sections using tabbed layouts.
• Updates OpenWebUI integration steps to use pre-exported Kokoro models pulled by OVMS.

• This command is under the CPU heading but no longer sets --target_device CPU. Because OVMS auto-detects the target device by default, the command may not actually run on CPU on systems with an available GPU.

docker run -d -u $(id -u):$(id -g) --rm -p 8000:8000 -v $(pwd)/models:/models:rw openvino/model_server:latest --rest_port 8000 --source_model dseditor/Qwen3-ASR-1.7B-INT8_OpenVINO --model_name Qwen3-ASR-1.7B-INT8_OpenVINO --model_repository_path /models

demos/audio/README.md:156

• This command is under the GPU heading but no longer sets --target_device GPU. With the default auto-detection, the actual device selection may not match the heading.

docker run -d -u $(id -u):$(id -g) --rm -p 8000:8000 --device /dev/dri --group-add=$(stat -c "%g" /dev/dri/render* | head -n 1) -v $(pwd)/models:/models:rw openvino/model_server:latest-gpu --rest_port 8000 --source_model dseditor/Qwen3-ASR-1.7B-INT8_OpenVINO --model_name Qwen3-ASR-1.7B-INT8_OpenVINO --model_repository_path /models

demos/audio/README.md:572

• This command is labeled CPU but does not set --target_device CPU. Since OVMS defaults to auto-detection, it may select a different device on systems with a GPU, making the CPU/GPU split misleading.

docker run -d -u $(id -u):$(id -g) --rm -p 8000:8000 -v $(pwd)/models:/models:rw openvino/model_server:latest --rest_port 8000 --source_model OpenVINO/whisper-large-v3-fp16-ov --model_repository_path /models --model_name whisper-large-v3-fp16-ov

demos/audio/README.md:579

• This command is labeled GPU but does not set --target_device GPU. With the default auto-detection, it may not run on GPU (or may fall back), so the example should be explicit.

docker run -d -u $(id -u):$(id -g) --rm -p 8000:8000 --device /dev/dri --group-add=$(stat -c "%g" /dev/dri/render* | head -n 1) -v $(pwd)/models:/models:rw openvino/model_server:latest-gpu --rest_port 8000 --source_model OpenVINO/whisper-large-v3-fp16-ov --model_repository_path /models --model_name whisper-large-v3-fp16-ov
