The microphone may be in your hand or on the sofa
Roku’s hands-free guidance tells the viewer to speak toward the compatible remote rather than the television. The remote is the intended microphone in that route. Speaking at the screen can therefore be a poor test of recognition.
Check that the actual remote supports hands-free voice and that the feature is enabled. A push-to-talk voice button does not by itself establish identical hands-free behavior.
Use an ordinary command comparison
Keep the remote nearby and use normal clear speech as Roku advises. Test a simple supported command before a long programme title. Reduce competing TV sound for the comparison rather than exaggerating every syllable.
If recognition succeeds but the requested equipment action fails, separate those stages. Understanding “volume up” and successfully changing the target receiver’s level are different results.
Keep the alternative usable
Roku also documents search through the on-screen keyboard. Retain that route when voice is unsuitable or a title is repeatedly misheard. A fallback does not imply the programme is unavailable.
Report the remote model, hands-free state and whether the command was recognized. This describes the actual input problem without making an unsupported claim about the television’s microphone or app support.
