When <Vpd k="NAME"/> is enabled for specific hosts, it only transcribes the audio of the specified hosts and ignores the others. The <Vpd k="NAME"/> service employs algorithms that remove the periods of silence and improve WER (Word Error Rate) of transcription. The processed audio is transcribed by the <Vpd k="NAME"/> engine and referred to as transcription duration. Agora charges for the transcription duration of all or specified hosts in the channel.

-Examples:
-- Let's say there is a channel existing for 10 minutes. There are 3 active hosts - A, B, and C - all in the unmuted state.
-- #3: If Spanish and Chinese LID is enabled for this channel at the start, the algorithm will remove 8 minutes of silent audio for host A, 7 minutes for host B and 7 minutes for host C. Therefore, the transcription duration is 2 + 3 + 3 = 8 minutes. the LID duration is 8 minutes, too, being the sum of 2 minutes for host A, 3 minutes for host B, and 3 minutes for host C.
+- Suppose a channel exists for 10 minutes. There are three active, unmuted hosts, A, B, and C.

Therefore, the transcription duration is 2 + 3 + 3 = 8 minutes. The LID duration is also 8 minutes, being the sum of 2 minutes for host A, 3 minutes for host B, and 3 minutes for host C.
 - If Spanish and Chinese LID is enabled for host A, then the transcription duration and LID duration are both 2 minutes.
 
 Notes:
-- The <Vpd k="NAME"/> transcription duration does not change if you enable more than 1 language.
-- If only 1 language is set for a channel or a specified host, the language detection will not start.
+- The <Vpd k="NAME"/> transcription duration does not change if you enable more than one language.
+- If only one language is set for a channel or a specified host, language detection does not start.

+## Translation fee
+
+When you enable real-time translation for a channel or a user, transcription is activated first. The transcription text is then translated to the target languages. The translation usage minutes are the same as the transcription usage minutes. The real-time transcription and translation usage and cost is shown in your monthly invoice. The unit price is as follows:
+
+|Billing item | Pricing, US$/1,000 minutes|
+|-------------|------------------|
+|Translation  | 8.99             |
+
+#### Example
+
+After you enable <Vpd k="NAME"/>: 
+- Host A speaks Russian for 2 minutes and remains silent for 8 minutes.
+- Host B speaks French for 3 minutes and remains silent for 7 minutes.
+- Host C speaks Russian for 3 minutes and remains silent for 7 minutes.
+- All hosts are silent for the first 2 minutes of the call.
+- Russian and French are translated to English.
+
+In this case, the total transcription minutes are calculated as 2 (Host A) + 3 (Host B) + 3 (Host C) = 8 minutes. The translation minutes are the same as transcription minutes. Agora charges 8 minutes transcription fee and 8 minutes translation fee. 
+
+Total cost = 8/1000*$16.99 + 8/1000*$8.99 = $0.136 + $0.072 = $0.208. 
+
+If you translate Russian and French to English and German, the translation cost is multiplied by 2:
+
+Total cost = 8/1000*$16.99 + 8/1000*$8.99*2 = $0.136 + $0.144 = $0.28.
