-Azure AI speech continues to advance in the field of text to speech technology with the introduction of neural text to speech high definition (HD) voices. The HD voices can understand the content, automatically detect emotions in the input text, and adjust the speaking tone in real-time to match the sentiment. HD voices maintain a consistent voice persona from their neural (and non HD) counterparts, and deliver even more value through enhanced features.

 ## Supported Azure AI Speech HD voices
 
+The Azure AI Speech HD voice values are in the format `voicename:basemodel:version`. The name before the colon, such as `en-US-Ava`, is the voice persona name and its original locale. The base model is tracked by versions in subsequent updates.
+
+Currently, `DragonHD` is the only base model available for Azure AI Speech HD voices. One version of the base model (`v1Neural`) is available for each voice persona. To ensure that you're using the latest version of the base model that we provide without having to make a code change, use the `LatestNeural` version.
+
+For example, for the persona `en-US-Ava` you can specify two HD voice values:
+- `en-US-Ava:DragonHDLatestNeural`: Always uses the latest version of the base model that we provide later.
+- `en-US-Ava:DragonHDv1Neural`: Always uses the `v1Neural` version of the base model. When we release a new version of the base model, you need to update your code to use the new version.

 The following table lists the Azure AI Speech HD voices that are currently available.

 ## How to use Azure AI Speech HD voices
@@ -79,14 +87,10 @@ Here are some key points to consider when using Azure AI Speech HD voices:
 - **Voice locale**: The locale in the voice name indicates its original language and region.
 - **Base models**:
   - HD voices come with a base model that understands the input text and predicts the speaking pattern accordingly. You can specify the desired model (such as DragonHDLatestNeural) according to the availability of each voice.
-- **SSML usage**: To reference a voice in SSML, use the format `voicename:basemodel`. The name before the colon, such as `en-US-Andrew`, is the voice persona name and its original locale. The base model is tracked by versions in subsequent updates.

 - **Temperature parameter**:
-  - The temperature value is a float ranging from 0 to 1, influencing the randomness of the output.
-  - You can also adjust the temperature parameter to control the variation of outputs.
-  - **Lower temperature**: Results in less randomness, leading to more predictable outputs.
-  - **Higher temperature**: Increases randomness, allowing for more diverse outputs.
-  - The default temperature is set at 1.0.
-  - Less randomness yields more stable results, while more randomness offers variety but less consistency.
