Customizing the user interface

On this page:

The IP VCR provides you with options for customizing the voice prompts, the viewing of thumbnail previews, and for controlling the auto-refreshing of user interface pages.

Note: the user interface (that is the text you see on the web interface of the IP VCR) can be localized by Codian or by your reseller. This type of customization is the localization of the text on the web interface and these online help pages. That is, the text has been translated into your local language. In the case where you have a localized unit, the Use localization package check box will be checked. For more information refer to Customization: more information.

The IP VCR allows you to type using any character set when entering text into the web interface. For example, when naming endpoints or users, you can use any character set you require.

Controlling the auto-refreshing of status pages on the IP VCR

To control the auto-refreshing of status pages on the IP VCR:

  1. Go to Settings > User interface.
  2. Choose the time interval for page auto-refreshes or, to stop pages from auto-refreshing, choose No auto-refresh.

    The status pages affected by this control are as follows:

    • Status > General
    • Status > Health

  3. Click Apply changes.

Controlling the display of thumbnail preview images

To control the display of thumbnail preview images on the IP VCR:

  1. Go to Settings > User interface.
  2. Choose whether you want to Show video thumbnail images or not. This controls whether or not you will see a preview of the recording on the Connections page.
  3. Click Apply changes.

Customizing voice prompts on the IP VCR

By default the IP VCR includes English voice prompts spoken by a female American voice. You may wish to replace these prompts with your own in order to change the wording, language or accent used. Alternative prompts may be uploaded individually using the web interface. Alternatively, a collection of voice prompts may be uploaded in one go by means of a resource package (see Uploading a customization package).

The customization of voice prompts is controlled via the web interface. Go to Settings > User interface. Refer to the sections below for details of the options available and for a description of the information displayed:

Using default US English voice prompts

The default set of voice prompts is provided in US English and is the standard set of voice prompts supplied with the IP VCR. These are spoken by a female voice in Americanized English. If your unit is using customized voice prompts and you want to return to using the default set of voice prompts:

  1. Go to Settings > User interface.
  2. In the Select customization section, uncheck Use customized voice prompts.
  3. If your unit was provided to you as a localized unit, uncheck Use localization package.
  4. Click Apply changes.

The default voice prompts will be applied immediately, although it may take a few seconds before everyone connected to the IP VCR is able to hear the new prompts.

Uploading a customization package

It is possible to upload a collection of alternative voice prompts to the IP VCR with a single upload operation, using a customization package. Such a package may have been supplied to you by Codian or one of its representatives, or you may have created the package yourself (see Downloading a customization package).

To upload a package:

  1. Go to Settings > User interface.
  2. In the Upload customization package section, click Browse and locate the .package file on your computer.
  3. Click Upload package.

The upload may take several seconds, depending on the size of the package file and the speed of your network connection. When the upload is complete, a status screen will be shown, displaying some or all of the individual voice prompt customizations included in the package if the upload was a success, or an error message if the upload failed for some reason.

To apply the uploaded customization package:

Note: If you were already using uploaded alternative voice prompts on the IP VCR, then these will be immediately replaced by those in the customization package. If a particular customized file is not included in the package, then any existing customization is unchanged. This allows customization sets to be built up using several different packages if required.

Viewing the available voice prompts

You may review the voice prompt customizations available in the table headed Installed voice prompts. The Installed voice prompts list displays all voice prompt customizations, providing details for those which have alternatives uploaded. Because these lists can be quite long, by default they are hidden. Instead, the number of customizations (files) available is shown. If any have been modified (meaning an alternative customization has been uploaded, either individually, or as part of a package), then this is indicated by an asterisk after the table name.

To expand any list to show all customizations, click show file details; you may subsequently hide it again by clicking hide file details.

In the expanded state, the table shows, for each customization, a description of the file, the standard IP VCR filename for the customization, and the length and date modified (uploaded) of alternative customizations present. Extra information is provided by the following symbols:

Uploading and downloading customized voice prompts

Refer to the sections below for details of further functionality provided by the Installed voice prompts list:

Uploading individual voice prompts

You may upload individual voice prompts. To do this:

  1. Go to Settings > User interface.
  2. In the Installed voice prompts section, locate the voice prompt file you require.
  3. For that voice prompt, click upload. You may do this regardless of whether an alternative customization has already been uploaded.
  4. You will be presented with a new screen, allowing you to locate and upload the customization of your choice. Click Browse button to locate the voice prompt file on your computer. Voice prompt files must be in the following format:
    • Microsoft WAVE (.WAV) format
    • 16kHz (16000Hz) sample rate
    • Mono
    • Uncompressed
    • Maximum 10 seconds long
  5. If you upload a file that is not in this format, the upload may fail or the voice prompt may sound distorted when heard by users. Use an audio editing package of your choice to make any conversions required. See Making the best possible recordings for how to obtain the best possible voice prompts for your IP VCR customization.

    Note that in addition to the 10 second length limit per prompt, there is a total length limit of 4 minutes for the full set of prompts. That is, if all samples were played back-to-back, it should take no more than 240 seconds.

  6. When you have located the file you wish to upload, click Upload customization. If the upload is successful, a page displaying the size of the file uploaded will be displayed; otherwise an error will be shown. If the upload fails, check your audio file matches the specification above before contacting your support representative.

Downloading individual voice prompts

You may wish to review a customization that has been previously uploaded to the IP VCR. To do this,

  1. Go to Settings > User interface.
  2. In the Installed voice prompts section, locate the voice prompt file you require.
  3. For that voice prompt, right-click download and choose Save Target As (or your web browser's equivalent operation). The file will be downloaded to your computer for reference.
Only alternative customizations can be downloaded in this way; the default voice prompts may not be downloaded. In addition, only customizations uploaded as individual files may be downloaded; those uploaded as part of a package may not be downloaded.

Downloading a customization package

Once you are satisfied with your customizations, you may wish to apply the entire set to another IP VCR. Rather than individually uploading the alternative voice prompts to each one, you may create a customization package.

To create a customization package containing all of the alternative voice prompts previously uploaded:

  1. Go to Settings > User interface.
  2. Click Download package at the bottom of the Installed voice prompts list. The customization package will be downloaded to your computer.

A package may only contain resources uploaded as separate files; those uploaded as part of another package may not be included. The package download option may be unavailable if no voice prompts qualify for inclusion.

Deleting customized voice prompts

If you are dissatisfied with a voice prompt that you have uploaded to the IP VCR, you may delete it in the following manner:

  1. Locate the voice prompt of interest in the list.
  2. Click the check box to the left of the voice prompt.
  3. Click Delete selected to remove the voice prompt.

Only alternative voice prompts may be deleted in this way; the default voice prompts cannot be deleted. If you delete an alternative customization, it will immediately revert to the default prompt, even if you have selected Use customized voice prompts at the top of the page.

You may wish to delete all customizations. To do this, press Delete all. Remember that you may revert to the default set of voice prompts without needing to delete any alternative customizations (see Using default US English voice prompts).

Making the best possible recordings

There are many factors to consider when recording alternative voice prompts in order to get the best results. Below is a brief summary of the points to bear in mind, though a more detailed document is available from Codian on request.

Recording format

It is best to make each recording with the ideal settings and hence avoid any sample-rate or resolution changes. As discussed, the ideal format is Microsoft Wave (.WAV) format, uncompressed, mono, at 16 kHz and 16-bit resolution.

If you are unable to make mono recordings, the IP VCR can convert stereo recordings.

Background noise

It is important to minimize background noise (hiss) as much as possible. This includes ambient noises such as road noise and slamming doors etc. but also try to keep fan noise and similar to a minimum.

When played back by the IP VCR, samples with background noise are very apparent.

Consistency

If possible, record all voice prompts in one session. This will ensure that all voice and background conditions remain constant and the recorded voice will sound similar from prompt to prompt.

Volume

Record prompts using a relatively constant loudness of voice. Although it may take some trial and error, the best recordings will result from speaking loud enough that the voice is recorded loudly compared to any residual background noise, but not so loudly that it sounds distorted when played back.
