Word Error Rate Solution

STEP 0: Pre-Calculation Summary
Formula Used
Word Error Rate = 1-(1/Expected Number of Transmission)^(1/Message Length)
Pew = 1-(1/En)^(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
Pew = 1-(1/En)^(1/m) --> 1-(1/4)^(1/1.16)
Evaluating ... ...
Pew = 0.697320668509567
STEP 3: Convert Result to Output's Unit
0.697320668509567 --> No Conversion Required
FINAL ANSWER
0.697320668509567 0.697321 <-- Word Error Rate

15 Data Analysis Calculators

Number of Bits Per Word
Go Message Length = (log10(1/Expected Number of Transmission))/(log10(1-Word Error Rate))
Undetected Probability per Word
Go Undetected Probability = (Undetected Error Probability*Success Probability)/(1-Undetected Error Probability)
Success Probability
Go Success Probability = (Undetected Probability*(1-Undetected Error Probability))/Undetected Error Probability
Undetected Error Probability per Single-Word Message
Go Undetected Error Probability = Undetected Probability/(Undetected Probability+Success Probability)
Input Waveform
Go Input Waveform = sqrt(Signal to Noise Ratio*Coding Noise)
Actual S by N Ratio at Output
Go Actual S/N Ratio at Output = Maximum Possible S/N Ratio/Noise Figure of Amplifier
Average Duration of Fade
Go Normalized LCR = Cumulative Distribution Function/Average Duration of Fade
Word Error Rate
Go Word Error Rate = 1-(1/Expected Number of Transmission)^(1/Message Length)
Expected Number of Transmission
Go Expected Number of Transmission = 1/((1-Word Error Rate)^Message Length)
Coding Noise
Go Coding Noise = (Input Waveform^2)/Signal to Noise Ratio
Information Bits
Go Information Bits = Number of Bits per Word-Header Bits
Header Bits
Go Header Bits = Number of Bits per Word-Information Bits
Capability of Error Correction Bits
Go Capability of Error Correction Bits = (Hamming Distance-1)/2
Expected One Transmission(E1)
Go Expected One Transmission = 1/(1-Word Error Rate)
Unsuccess Probability
Go Word Error Rate = 1-Success Probability

Word Error Rate Formula

Word Error Rate = 1-(1/Expected Number of Transmission)^(1/Message Length)
Pew = 1-(1/En)^(1/m)

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 Pew 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 (En) & 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 Pew = 1-(1/En)^(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 (En) & 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.
