 Custom Neural Voice is based on the neural text-to-speech technology and the multilingual, multi-speaker, universal model. You can create synthetic voices that are rich in speaking styles, or adaptable cross languages. The realistic and natural sounding voice of Custom Neural Voice can represent brands, personify machines, and allow users to interact with applications conversationally. See the [supported languages](language-support.md?tabs=stt-tts) for Custom Neural Voice.
 
@@ -37,9 +37,9 @@ Before you get started in Speech Studio, here are some considerations:
 - [Design a persona](record-custom-voice-samples.md#choose-your-voice-talent) of the voice that represents your brand by using a persona brief document. This document defines elements such as the features of the voice, and the character behind the voice. This helps to guide the process of creating a custom neural voice model, including defining the scripts, selecting your voice talent, training, and voice tuning.
 - [Select the recording script](record-custom-voice-samples.md#script-selection-criteria) to represent the user scenarios for your voice. For example, you can use the phrases from bot conversations as your recording script if you're creating a customer service bot. Include different sentence types in your scripts, including statements, questions, and exclamations.

+1. [Create a project](how-to-custom-voice.md) to contain your data, voice models, tests, and endpoints. Each project is specific to a country and language. If you are going to create multiple voices, it's recommended that you create a project for each voice.
 1. [Set up voice talent](how-to-custom-voice.md). Before you can train a neural voice, you must submit a recording of the voice talent's consent statement. The voice talent statement is a recording of the voice talent reading a statement that they consent to the usage of their speech data to train a custom voice model.
 1. [Prepare training data](how-to-custom-voice-prepare-data.md) in the right [format](how-to-custom-voice-training-data.md). It's a good idea to capture the audio recordings in a professional quality recording studio to achieve a high signal-to-noise ratio. The quality of the voice model depends heavily on your training data. Consistent volume, speaking rate, pitch, and consistency in expressive mannerisms of speech are required.
 1. [Train your voice model](how-to-custom-voice-create-voice.md). Select at least 300 utterances to create a custom neural voice. A series of data quality checks are automatically performed when you upload them. To build high-quality voice models, you should fix any errors and submit again.

You can also create up to 10 custom styles by providing style samples as additional training data for the same voice.
