According to the SMCR (Source-Message-Channel-Receiver) model, problems in communication can arise when the speaker fails to encode the message effectively. If the speaker does not clearly articulate their thoughts or use appropriate language for the audience, the intended meaning can be lost or misunderstood. Additionally, if the speaker lacks credibility or fails to engage the audience, the message may not resonate or be perceived as valid. This breakdown can lead to misunderstandings and ineffective communication overall.
