Word Error Rate Solution

STEP 0: Pre-Calculation Summary

Formula Used

Word Error Rate = 1-(1/Expected Number of Transmission)^(1/Message Length)
P_ew = 1-(1/E_n)^(1/m)
This formula uses 3 Variables

Variables Used

Word Error Rate - Word Error Rate (WER) in wireless communication refers to a metric used to measure the accuracy of speech recognition or automatic speech recognition (ASR) systems.
Expected Number of Transmission - Expected Number of Transmission refers to the average number of times a packet or data transmission needs to be sent from a transmitter to a receiver in order to achieve successful delivery.
Message Length - Message Length in wireless communication refers to the size or duration of a data transmission or message sent over a wireless network or channel.

STEP 1: Convert Input(s) to Base Unit

Expected Number of Transmission: 4 --> No Conversion Required
Message Length: 1.16 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_ew = 1-(1/E_n)^(1/m) --> 1-(1/4)^(1/1.16)

Evaluating ... ...

P_ew = 0.697320668509567

STEP 3: Convert Result to Output's Unit

0.697320668509567 --> No Conversion Required

FINAL ANSWER

0.697320668509567 ≈ 0.697321 <-- Word Error Rate

What is Transmission Mode?

Transmission mode refers to the mechanism of transferring data between two devices connected over a network. It is also called Communication Mode. These modes direct the direction of the flow of information.

How to Calculate Word Error Rate?

Word Error Rate calculator uses Word Error Rate = 1-(1/Expected Number of Transmission)^(1/Message Length) to calculate the Word Error Rate, The Word error rate (WER) is defined as a common metric of the performance of speech recognition or machine translation system. The general difficulty of measuring performance lies in the fact that the recognized word sequence can have a different length from the reference word sequence (supposedly the correct one). Word Error Rate is denoted by P_ew symbol.

How to calculate Word Error Rate using this online calculator? To use this online calculator for Word Error Rate, enter Expected Number of Transmission (E_n) & Message Length (m) and hit the calculate button. Here is how the Word Error Rate calculation can be explained with given input values -> 0.697321 = 1-(1/4)^(1/1.16).

FAQ

What is Word Error Rate?

The Word error rate (WER) is defined as a common metric of the performance of speech recognition or machine translation system. The general difficulty of measuring performance lies in the fact that the recognized word sequence can have a different length from the reference word sequence (supposedly the correct one) and is represented as P_ew = 1-(1/E_n)^(1/m) or Word Error Rate = 1-(1/Expected Number of Transmission)^(1/Message Length). Expected Number of Transmission refers to the average number of times a packet or data transmission needs to be sent from a transmitter to a receiver in order to achieve successful delivery & Message Length in wireless communication refers to the size or duration of a data transmission or message sent over a wireless network or channel.

How to calculate Word Error Rate?

The Word error rate (WER) is defined as a common metric of the performance of speech recognition or machine translation system. The general difficulty of measuring performance lies in the fact that the recognized word sequence can have a different length from the reference word sequence (supposedly the correct one) is calculated using Word Error Rate = 1-(1/Expected Number of Transmission)^(1/Message Length). To calculate Word Error Rate, you need Expected Number of Transmission (E_n) & Message Length (m). With our tool, you need to enter the respective value for Expected Number of Transmission & Message Length and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Word Error Rate?

In this formula, Word Error Rate uses Expected Number of Transmission & Message Length. We can use 1 other way(s) to calculate the same, which is/are as follows -
